Saying “Nasty Gal” makes us feel dirty, and we like. The boutique’s in-your-face name demands your attention—and the awesome inventory keeps you coming back for more. Founded in 2006 by stylist Sophia Amoruso, Nasty Gal offers a spunky selection of both handpicked vintage wares and on-trend items from some of the hottest street culture designers out there. Given Amoruso’s interests (she enjoys “a good Salade Nicoise, a sturdy pair of platforms, and twirling around the studio every so often while blasting disco”), and musings on her blog, you can tell the girl lives and breathes the NG attitude and looks just like the girl she shops for. And that girl is sexy, fun, and always down for a good party—especially the party, New Year’s Eve. Here are a few dresses we’ll want to be in for the big countdown.
