When we heard the news this past fall that Jennifer Lopez would be returning to join Season 13 of American Idol, we were beyond excited– and that was well before we knew what was in store for her wardrobe. This season, our April cover girl has been satisfying our insatiable appetite for fashion by upping her wardrobe game on the show, as proven on Wednesday.

The singer and judge stole the show last night in this mint colored Safiyaa dress, paired with nude, embellished Jimmy Choo pumps, and we chatted with her stylist for the inspiration behind the look. “We picked something tonight that felt like fresh, reminiscent of Spring,” said Rob Zangardi. “[We chose this] sophisticated dress paired with a loose side braid.”
