She sizzles in sequins and looks phenomenal in a neon onesie, so it comes as no surprise that on Thursday night’s episode of American Idol, judge Jennifer Lopez switched up her ensemble with another bold (and completely different) look. This time, the star opted for a white Michael Kors chain front dress from the Resort 2014 collection, which she accented with gold metallic Casadei pumps, putting us in the mood for summer (even if we’ve been wearing whites all winter long).

Lopez completed her look with sleek strands. “Tonight’s hair was an homage to the 1960s,” says hairstylist Lorenzo Martin. “We kept it simple and sleek to compliment her outfit.”
