This troper works as a cashier with her older sister and younger brother. People routinely ask if we're twins, despite the fact that the sister is in college and I'm in high school. On another note, people ask this troper if her (12-year-old) brother is her son, although this troper is 16. squick.

This troper has an elder twin sister, who is female. This troper is male. People still ask whether we're identical.

As strange as it may sound, this editor's sister bears a striking resemblance to him. Made even stranger by the fact that she is a year and a half younger than I am. In fact, many have asked if we're twins, apparently confused about how identical twins work. Of course, being in the same grade might have something to do with the confusion, making it look like we're fraternal twins.

Another troper has a friend with a younger brother just like this.

Are you talking about me? People used to think me and my sister were twins.

People used to say this about me and my sister all the time, much to our annoyance (we didn't get along much back then). Also my older brother looks SCARILY identical to my Dad based on photos of my Dad when he was my brother's age.

This troper and her two-years-younger brother have been mistaken for twins, but this is usually because this troper looks remarkably like a boy when her hair is short.

This troper is regularly mistaken for his six-years older brother. ''By his mom''.

This troper has cousins who are 8 years apart in age (they're sisters), but look like they could be clones.

Are you my cousin? Because that describes my sister and I perfectly.

This troper has a disturbingly similar face to that of her two-years-younger sister (the disturbing comes from the fact that I loathe her). Of course, I was always tall for my age and she was always short for hers, so we've never really been confused for each other. Even less so nowadays, since I'm four inches taller and more developed, and the blondish hair we had as children turned into strawberry blonde for me and light brown for her.

This troper went to middle school with a set of identical twins. The half identical twin was their younger brother, who was two years younger than the twins, but looked like a third twin. Fast forward 5 years and the twins and their younger brother STILL look like triplets.

One editor had a friend who was the oldest of six girls. All the girls looked like various-size editions of each other and their mother, to the point that it was rather easy to confuse any two of the girls who were near each other in age/size.

This troper's husband and his sister are so alike in appearance that they have been mistaken for twins. Compounding the error, their birthdays are three days apart and they usually had joint birthday parties growing up.

This troper used to know a set of fraternal twins, a boy and a girl. If you made the boy's hair longer or the girl's hair shorter, they would have looked ''exactly'' alike.

This troper IS a fraternal twin, and while there's a resemblence between him and his sister (such as you'd expect from, you know, siblings) we don't look very much alike. So for the love of god you'd better not ask whether we're identical...

Oh, and we went through elementary school with another set of fraternal twins. With a minimal amount of effort the brother and I could pass for identical twins. Always good for a laugh.

This troper has ''three'' sets of these (kids of my cousins) - one is a pair of brothers, the other two pairs are brother and sister; in all three pairs the age difference is about two years. The odd thing about the two brother-sister pairs is that the Pair A siblings look like exactly their father (their mom jokes that she's breeding clones of her husband) while in Pair B the boy and his look-alike older sister resemble their mother while his twin sister looks like her father.

As a reverse of this, both sets of ''actual'' twins in my family are fraternal; in addition to the above pair, the other set consists of my youngest cousins, two brothers who are so different in appearance that one looks about three years older, much to his joy and his brother's chagrin.

Additionally, I had a friend who was essentially a clone of her older sisters. Her only brother, on the other hand, looked like he'd been adopted - their father was white, their mother was Asian; the girls got both parent's looks while the boy got only his mother's.

This troper and her eighteen-month-older brother. As well as her twenty-four-month-younger brother. Hell, we've been mistaken for triplets.

This troper and her brother (who's sixteen months older than her) are regularly mistaken for twins, which is reasonable enough because we're close to the point of finishing each other's sentences. We just go with it; we enjoy our pseudo-twinness in full.

This troper has a brother who's four years older than her. We're both blonde and around the same height, and apparently we're clones of each other. This makes my brother very unhappy since he's nineteen and I'm fifteen, and people think we're both seventeen.

This troper has twin cousins he didn't know were fraternal until they were in ''college''. He's still not sure if he can tell them apart.

Upon meeting my family (mother, father, younger sister by two years, younger brother by four) a friend asked me if my family and I were really just clones.

I got 2 examples, one involving myself. My sister, who is like two years younger than me, but almost just as tall, but has more hair and no glasses.... People are able to identify her as my sister almost immediately because we look so much alike, despite obvious differences. And then there's my best friend whose brother is like 2 years older and my friend is basically his "Mini-Me", besides hairstyle differences. Eerie

Averted with This Troper. I'm an identical twin.

Whenever ThisTroper and his next-younger brother go out, we often get asked if we're twins. We're actually a year and a half apart.

This troper and his seventeen-months-younger brother looked a lot alike as small children - less so now, as this troper is much skinnier than his brother and also ''shorter,'' and his brother's the only person in the family who doesn't need glasses.

He also knows two sets of those stair-step siblings - one male, one female. One of the male ones looks disturbingly like a shorter version of this troper.

My mother and her younger brother (my uncle, obviously) are a year and a half apart in age. Looking at pictures of them as little kids, I would've mistaken them for twins had I not known who they were, and a lot of people did think they were twins back then.

I don't know if this counts, but I have a cousin who is six years older, but at times, people get us confused. Despite me having longer hair and being almost a foot taller.

This troper actually ''is'' a literal half-identical twin. It's called polar body twinning.

This troper is as well, if family history is to be believed. When the doctors who deliver you aren't sure if you're identical twins until they actually compare DNA, it's pretty clear something like this is going on.

Given that there is one pair of (possible) polar-body twins, who would be in elementary school right now... Hmm.

This troper is frequently mistaken for her sister, who is two years younger, especially by her parents. It doesn't help that her real name is Twin Naming}} two letters different from her sister's name. They even began introducing themselves as identical twins just to stop the questions.

This troper has been mistaken for both his older brother and his younger sister, people have asked if my brother and i are twins.

I also have two other younger sisters who actually are (similar but non-identical) twins. When they were younger friends of our parent used to have to ask if it was the bigger twin and the older sister were the twins, or the actual twins. Now the two twins are fifteen, and have grown into their own independant looks (and i half-suspect that they're going out with the same guy (i try not to look for fear of going blind)) and they've recently been cast in a modern retelling of Hamlet, playing... ThoseTwoGuys!

And on top of THAT their parts in the play add a very odd angle to the roles. Think about, Gertrude sends two twin female spies after Hamlet to, ahem, "talk sense into him". And at one point they utter the line "my lord you once did love me". I've told the director about this reading of the parts but he insists I'm imagining things, but i've asked other actors in the play and they've noticed it too!

But to be fair, in this production Hamlet spends most of his time taking teh piss out of them, going so far as to frequently and deliberately mistake them for men (cos he calls them sirs in the original text, which we're using(abridged)).

His grandmother was also a twin (identical), and they were name Ita and Rita. And on top of THAT they also had two Other friends named Rita, and Ita was used to being adressed as Rita. So if they were all sat together and someone asked for Rita...

He also has a cousin who has an identical cousin. They're same height, similar faces, similar styles, similar glasses. It is actually frickin uncanny.

Myself, my older brother and no less then two of our uncles would be mistaken for each other if you where shown a photo of each of us at four. We all still look amazingly similar.

A friend of this troper's and her younger sister were often mistaken to be twins including once on a day out, by a passerby. Said passerby failed to notice this troper and her identical twin walking directly behind them. Go figure!

Inverted by this troper and her sister. We're identical twins, yet due to a case of twin-to-twin transfusion in utero, I'm several inches taller, generally more stronger, my hair is thicker, and we've pretty much always maintained a 3:2 body weight ratio with me being the heavier and her being very scrawny. I'm the more outgoing one, but we have about the same intelligence and like most of the same stuff. We usually have to inform people that we are, in fact, twins, and this usually receives looks of shock. (Is there a separate trope for non-identical identical twins, out of curiosity?)

Me and my brother are somehow mistaken for each other, even though he's 2-3 years younger. And I reckon I look a lot like my dad. Except I'm taller than him.

This troper's older sister and mother look exactly the same when they were children, to the point where it's difficult to sort pictures. This troper doesn't suffer from this trope, thankfully. It helps that this troper is the only one who doesn't need glasses, too.

This troper has two friends who have successfully passed themselves off as identical twins despite being a guy and a girl and not at all related.

This troper was at a friend's house when she noticed a photo on the fridge. "You played softball?" "That's not me. That's my ''stepcousin''."

This troper once knew a pair of siblings that actually ''were'' twins, and were damn near identical. However, on the first day of classes, they explained everything. However, they were startlingly alike, as they were both absolutely horrible people.

People say This Tropette looks a lot like her ''nine-years older'' sister.

This Troper and his younger (by 16 months) brother were often mistaken for each other while we were children/teenagers. Nowadays he has long hair and a slightly heavier build. Also, I've always had lighter hair and blue eyes while he has both darker hair and brown eyes.

This Troper had a friend in elementary school who people kept assuming was my twin sister.

This Troper has a 7-years-older sister who she looks an awful lot like (at least, when you see younger pictures of her sister) and this sister is easily recognised as her sister. She has also seen a photo of her dad when he was younger and instead saw ''herself'' in it.

This troper's mom had an embarassing moment when she couldn't say wether the kid portrayed in an old picture was me or my nine years older brother (it actually was him, and he was at least ten in the pic).

There multiple occurances of this when this troper's boyfriend's mum was picking photos to show at his brother's birthday party. They haven't let her hear the end of it since.

This troper's sister and ''daughter'' look freakishly alike. If you lay pictures of them at the same age side by side, it's nearly impossible to tell them apart. It's not fair! I did all the work!

Happened twice with this troper. When I was younger, my mother and I were mistaken for sisters. Another time, when I had just gotten my glasses, I was quite surprised to see my four-years older brother still at ho-- Oh wait, that was just me looking at my ''own reflection''. Though it's also partially because the upper part of my face couldn't be seen.

This troper is different enough in build (she's oddly masculine-looking while he's oddly feminine, in fact) and hair length to be distinguished from her brother. It's a different matter when it comes to our voices, clothes, names, aspects of our faces, and mannerisms.

This troper has two cousins who are seven and fourteen years younger than her respectively. Both younger cousins, (who are sisters,) looked like little "me"s as small children. It's too the point that the one that is fourteen years younger than I am saw a picture of me when I was two or three and thought it was her, (and really, it could've passed for her.) Needless to say, they are often mistaken for my sisters.

In addition, my Grandmother's siblings all have the same face. When I was younger, I saw a picture of all 11 of them together and exclaimed "It's a bunch of Grammy's!"

I wish I could show you the evidence, and for privacy's sake can't of course. Back in elementary school I had two classmates who were fraternal twins. I never noticed it at the time, but looking back at my old yearbooks I came to the revelation that the girl looked like her brother in a wig! To add to all this, they were named Alex and Alicia.

This Tropette has found a Half Identical Twin in her girlfriend. It's creepy how much we look alike and we always get weird looks when we start to get kissy or whatever in public. It's like incest but with out the real factor! (It's still creepy as hell and its fun to watch other people react)

This Troper knew a pair of HalfIdenticalTwins in elementary school, Storm and Emma Putzke (hope that was spelled right). They were visually indistingushable until Emma grew her hair out a bit.

This Troper's entire immediate family (both parents, his sister, and his brother) came to pick him up from school one day and a buddy was feaked out because everyone in my family had "the same face".

Unfortunatley, this troper and her twin brother are ACTUALLY half-identical biologically. We're just good looking mutants... >_>

Two girls (they were sisters) that used to be in this tropers art class. Though one was 2 years older than the other (and at least a foot taller), they were completely indistinguishable aside from the height. What made matters worse is that they have extremely similar voices and personalities.

Before this adopted troper got really fat and his sister got really skinny, they were often mistaken for biosiblings. Eyes, hair and natural skin tone not just the same color, but the same shade, really. Round faces, cleft chins, even similarly-shaped hairlines. And she's the younger one, so this wasn't a decision our parents made. Just coincidence.

This troper's sister and (male) cousin are regularly taken for twins. They exploited this shamelessly in the year where she was old enough to get into pubs and he wasn't: "ID?" "I can't find it, but we're twins."

This troper (female) is often said to look much like her 2-years older BROTHER.

Are you me, by any chance?

This Troper looks a lot like her friend, except for the fact that he is male, and she is female, and he is a lot taller. We look kinda alike, and are always together, and have a similar personality. Most people who dont think we are twins, think we are boyfriend and girlfriend...so id much rather have them think he is my brother.

This Troper (who shall remain unnamed) was friends with DavidCross's sister, before he got famous. Now that he makes regular media appearances, I get to see Julie's face with his shaved head all the time.

This Troper subverts this by looking absolutely nothing like her younger sister but they are still mistaken for twins/close friends because I have a 'young face' while my sister can look anywhere from a year or so older than her actual age to five years older depending on her clothes and make-up.

There is a male cat and a female cat living outside this troper's house. They only differ in gender and slight differences in color. her(this troper's) family isn't sure if they're from the same litter (twins, technically) but she believes so.

This Troper (who has forgotten her handle) has an 18-months-younger brother who people say looks extremely similar to her. It doesn't help that her hair is shorter-than-shoulder length and his is only slightly shorter than that, both the same shade, or that he's shorter than her only by about a centimeter, or that they have the same skin shade, or that they have the same exact eyebrows and eyelashes, or that the only discernable difference is that his eye color is a lighter brown than hers and she wears glasses.

This Troper is male, with a female fraternal twin. When we were little, even our PARENTS couldn't tell us apart. Now, I've dyed my naturally-blonde hair a reddish-violet and pierced my eyebrow and lower lip. My sister still has her natural hair color but curls it and wears it (slightly) longer and has no facial piercings (she has a belly ring, but if she's wearing something to reveal it, it's pretty obvious she's not me XD). Still, anyone who doesn't see us regularly almost always get us confused. I suppose it's justified, since we have very similar facial features, but still, it's a bit infuriating to be mistaken not only for a girl, but for your highly feminine sister...

This troper knows a pair of twins who look almost identical, even though they are fraternal.

This troper's former teacher bears a strong resemblance to her brother, and they're often mistaken for twins, but aren't. Said teacher finds it particularly silly because, as a biology teacher, she knows that's very unusual for fraternal twins to look alike.

This troper's five-years-younger sister looks like a twelve-year-old version of her, the only difference being the sister's eye colour and height. We even sound identical; our own parents can't tell us apart on the phone.

This troper is almost identical to his father when he was younger. Also, two of my cousins, brothers, look identical. Well, sort of. There's an eight year age difference, but in pictures that they're the same age, they look identical.

This troper has two neighbors. They are eight-year-old fraternal twins who look exactly the same except for gender. Their mom gets asked whether they are identical ALL. THE. TIME.

For this troper, the hypothetical situation on the mainpage - identical twins where one gets a sex-change operation - is not hypothetical at all, as he knows a twin pair who have undergone this. This troper actually has no problem telling them apart, because they exemplify the TomboyAndGirlyGirl dichotomy (and, if memory serves, did so even pre-op). This just goes to show you one thing: HalfIdenticalTwins only work if the twins are ''trying'' to look identical. (Which this troper can ''also'' attest to because he knew the sex-change twins from choir, and the choir's ''director'' is a twin, and ''they'' are so identical it's not even funny...)

Incidentally, this troper has sung in four choirs ever in his life. ''Three'' of them are run by twins. What're the odds of that? (One set of "So identical I can only tell because one of them isn't waving a baton," one set of "One's getting pauchier so I can kind of tell them apart," and one set of "Totally easy because one of them shaved his head".)

This troper is told that he looks very much like his six-years-younger brother physically, but that our ''body language'' is totally different.

This troper and his twin sister look ''disturbingly'' like cross-dressing versions of each other.
