The best things always come in twos—or at least that’s true of the wardrobes of high-flying sisters. Take a gander at the leggy Aldridge duo, Ruby and Lily, who inject a high-octane round of supermodel glitz while respectively wearing a jumpsuit and minidress slathered in sequins. Looking for more of a streetwear influence? There are It girls Simi and Haze Khadra to deftly delve into the cheeky world of designer knockoffs, donning riffed-on logo shirts and racing leather jackets.
Prefer your model sisters to come with different styles? Look to the Hadids, where Gigi makes a case for a pretty-in-pink palette in a teeny shift dress, while Bella is every inch the sophisticate in an all-cream look. Even the Jenners have gotten into the sister-sister trend, with a fur stole–wearing Kendall and gladiator sandal–clad Kylie coming together to snap a mirror selfie. Too much glitz and glam? The Soles twins are as charming and cute as they come, with their young, fun look of chokers, shearling, denim, and matching high ponytails. No sister? No problem! Get the double-take look here.
