Someone do a DNA test, because Mary-Kate and Ashley Olsen are supposedly fraternal — aka, not identical — twins. Madness. (That means their song “Identical Twins” off their hit record, Brother For Sale, was a lie.) They certainly look enough alike to pass for each other, and we have a hard time telling who is who. After some scientific calculations; many years of watching Full House, Passport to Paris, and So Little Time; and a little help from this video, we think we may have cracked the code on how to tell the Olsen twins apart.
Check their hands.
Mary-Kate is left-handed; Ashley is right-handed. If you see a twin holding a gargantuan coffee in her left hand, it’s likely MK.
Gaze into their eyes.
Ashley’s peepers pop, while Mary-Kate’s aren’t quite as wide.
Ashley is taller. By less than an inch, but still.
This mostly helps the twins are side-by-side, as both girls keep their brows pretty well groomed, but Mary-Kate keeps her brows a bit thinner.
The designers have different styles. While Ashley opts for more simple, feminine ensembles, Mary-Kate piles on the accessories, often wears darker colors, and is edgier.
Look at the lips.
Both twins enjoy making the duck lips, but MK does it more. So if you see one of them doing it, it's a 75% chance it's Mary-Kate. Plus, Ashley has more pillow-y bottom lip.
