In the ’90s, knee-high socks were a big deal. After Cher Horowitz wore them in Clueless, they became a fashion-girl staple. But when Britney Spears wore them in her video for “…Baby One More Time,” they pretty much exploded. We haven’t seen them make a huge appearance since then, but we’re predicting their imminent return. Fashion girls have been snapped wearing them all over the street style scene, and if the spring runways are any indication, they’re also a cool piece to style underneath tall mesh boots like we saw at Dior’s S/S 18 show.
