* Played With in ''A Monsterous Holiday'' twins April and May have a single pigtail, sometimes highlighted in different colors, which oddly enough made them seem more like SingleMindedTwins that happened to have divided GirlishPigtails given their tendency for TwinBanter.

* In ''Wedding Rehearsal'' (1932), when the Roxbury twins are first seen (from behind, entering adjoining rooms), they would be indistinguishable from each other were it not for their similar-but-different interest in pets - one favours dogs, the other cats.

* ''Literature/MidnightTwins'' is a trilogy about seer twins, one who can see into the future and one into the past. Meredith, aka Merry, is cheerful and girly. Her hair is parted on the right, she's right-handed, and she has two piercings in her right ear. Mallory, aka Mally, is a tomboyish loner with all of the aforementioned characteristics on her left side.

* Mona and Lisa ''Series/HalloSpencer have different hairstyles Mona has pigtails while Lisa has a ponytail.

* ''WesternAnimation/TheLittleMermaid'': Flotsam and Jetsam may or may not be twins, but they look exactly alike except for one thing which isn't that noticeable; both have one yellow eye and one white eye. Flotsam's left eye is yellow while his right eye is white, and for Jetsam, the reverse.

** In "[[Recap/SabrinaTheTeenageWitchS3E18SabrinaTheTeenageWriter Sabrina the Teenage Writer]]", Sabrina, having to write a story for English class, chooses SpyFiction and bases all her characters on real people, but little did she know at the time, she was using Hilda's old magic typewriter for the assignment, which ultimately caused her characters to come alive. Worse yet, due to the fact that she was too tired to write the ending, wherein the villain blows up her school, because she was working with a magical typewriter, her characters cannot die, because when that happens, [[TakingYouWithMe their real-life counterparts die, too]], and the only way said characters will disappear is when Sabrina has written a proper ending to the story. The characters in Sabrina's story are based on the following people: the villain, Dr. Bad, on [[EvilPrincipal Mr. Kraft]] ([[BaldOfEvil bald]], [[EvilCripple in a wheelchair]], having no glasses and sporting an eyepatch), Dr. Bad's lackey, [[DarkActionGirl Lydia Kissandkill]], on [[AlphaBitch Libby]] (she has a Sci-Fi Bob Haircut and black cheerleading uniform), the hero, Derek Kink, on Harvey (wears a suit, has his hair in a short-back-and-sides and has [[PungeonMaster a major knack for cracking one pun after another]]), Derek's partner, [[ActionGirl Vivian Soontodie]] on Valerie (having longer hair and wearing a catsuit) and Derek's GadgeteerGenius, Mrs. Doohickey on [[CoolTeacher Mrs. Quick]] (wears her hair up and has glasses and a lab coat).

* Henrik and Daniel Sedin, captain and alternate captain of the Vancouver Canucks from 2000--2018. Apart from both twins having diifferent jersey numbers, while most players' jerseys have just their last names on the back, but the Sedin brothers' featured their first initials as well. And of course, Henrik's jersey had a C on the shoulder in the front to denote him as captain, while Daniel had an A denoting him as alternate captain.[[note]]Ice hockey teams typically have two or three alternate captains who can serve in that role when the designated captain is not on the ice.[[/note]] Despite all this, there were ''still'' occasions where [[https://www.youtube.com/watch?v=NKbrthdHIPw the wrong Sedin got sent to the penalty box]].

* Apart from having different tattoos on their arms, American football players Shaquill and Shaquem Griffin of the Seattle Seahawks are also distinguished by the fact that Shaquem is missing his left hand, which was amputated when he was four, as the limb was entangled in amniotic bands before birth and never properly developed.

* Parents to newborn identical twins learn to differentciate between them by the shape of their belly-button, which is a scar and thus unique to everyone.

* Keith and Kevin Hodge, AKA the Hodgetwins, are identical twin brothers who are famous for their Website/YouTube content. Despite their identical looks, they can told apart by particular details. Keith has a small horizontal scar on his forehead, TsurimeEyes that represent his more serious demeanor, and a slightly deeper voice than Kevin's. Kevin has a small vertical scar on his forehead, TaremeEyes that represent his more laid-back demeanor, and a slightly higher-pitched voice than Keith's.

* Hamish and James Marshall are identical twins who played cricket for New Zealand, before the introduction of names and numbers in first-class matches or test matches (games where everyone on both teams wears white). As a subtle tag, James wore a red wristband and Hamish wore either blue or went without. However, this didn't show when the twins batted together - although they usually played with different coloured grips on their bats, there were instances when they matched from head to toe. The result of this was scoreboard operator giving up tracking their individual scores, and the twins admitting their career runs probably have a solid margin of error. At the end of his New Zealand career, Hamish moved to the UK to play County cricket, able to do so because of an Irish grandparent - meaning their 'twin tag' went from being the colour of their wristbands to the colour of their passports.

* In ''Literture/ACertainMagicalIndex'', Touma distinguishes Mikoto from her clones by the fact that most of the time, the clones are wearing goggles to help them see electrical fields, something Mikoto can do naturally. Mikoto also wears ModestyShorts under her skirt, while her clones don't. After a while he realizes that waiting for a strong breeze and looking up a girl's skirt is going to get him into trouble eventually, so he decides to buy a ring for Misaka 10032 to help identify her from Mikoto and the other clones. He quickly realizes that a ring might be too small to be easily spotted, so he decides to get her a necklace instead. But Misaka has been told that a ring is a gift from a boy who likes you, so she insists on it.

* ''VideoGame/FinalFantasyXIV'' has the twins Alphinaud and Alisaie Leveilleur whilst [[HalfIdenticalTwins one is a teenage boy, the other a teenage girl]] they still look similar enough to be confused for one another. The both have [[IdiotHair prominent cowlicks]] in their hair but Alphinaud's points left and Alisaie's points right. When they were first introduced this was the main way to tell them apart especially as they were both Arcanists who wore blue, until ''Stormblood'' when [[TwinDesynch Alisaie gets a job switch and starts wearing a light tan outfit]] and then later in ''Shadowbringers'' starts favouring red and Alphinaud sticks with blue.

* Dante and Vergil of the ''VideoGame/DevilMayCry'' series. Dante has a relatively simple red longcoat in all his appearances and wears his hair loose. Vergil wears a far more elaborate blue coat and keeps his hair slicked back, though occasionally (such as toward the end of their first fight in ''VideoGame/DevilMayCry3DantesAwakening'') it falls out of place, making it look identical to Dante's.

* Although ''canonically'', [[EvilTwin Beyond Birthday]] [[IJustWantToBeYou dresses exactly the same as L]] in ''LightNovel/AnotherNote'', {{Fanon}} will ''usually'' either depict him as [[BloodIsTheNewBlack splattered with blood]] and/or [[ColorCodedForYourConvenience wearing a black shirt]], particularly in {{Cosplay}}, or works where he and L will appear together. Also, BB is usually (though not always) depicted with neater hair than L, for the same reason.
