Yesterday in Berlin, the pop singer dressed in a plaid pleated skirt and jacket combo by Alice + Olivia to continue her global “Killer Queen” promotional tour. While she looked ecstatic to be posing with her new bottle, her outfit made her look like an overgrown schoolgirl. She slipped on a white Dolce & Gabbana blouse underneath her red-and-black pieces, added a twee black bow to the jacket, and wore Christian Louboutin booties with knee-high socks. Her large golden hoop earrings and an impressively tight crown braid finished the look off. Nineties reference? Who knows anymore.
