A plunging back is arguably one of the sexiest trends (see Jourdan Dunn as proof), as it's an unexpected way to show some skin. To make this come-hither style live up to its full potential, skip the gold eye makeup and employ a gold-infused body oil, like Shiffa Luxury Gold Body Glow, $68, instead. This incredibly nourishing formula contains jasmine, lemon, orange and argan oils, along with real gold pieces, to make skin look healthy and youthful.
