Don't Miss:

Jennifer Lopez wowed at this year’s Grammys in one of the night’s sexiest dresses—a billowing satin number complete with a thigh-high slit—a piece by Belgian designer Anthony Vaccarello. While the name may sound new to many, he’s quickly becoming a go-to for the music world, with both Lopez and Cassie choosing his skin-baring, super sexy designs (which are also available on luisaviaroma.com). Just yesterday, Vaccarello debuted his latest collection for fall during Paris Fashion Week (seen right), boasting another lineup of LBDs and racy gowns sure to raise the sultry level of any red carpet. Be on the lookout—we expect to him dress lots more celebrities soon.
