Tapping into this season’s ’80s nostalgia doesn’t have to mean wearing taffeta from head to toe. Isabel Marant has brought the power shoulder up to speed in the form of this sexy one-sleeved top. Temper the drama of the ruched leather trophy piece by pairing it with classic skinny jeans and a belted blanket coat: sexy, but couldn’t-care-less-about-it is the look you’re going for. Finish with western boots and a soft leather bag by day (anything structured is too uptight), and swap in a quilted chain-handle bag and knee-high slouch boots after dark. Oh, oui.
