Katy Perry and John Mayer had a day-and-night date in NYC, and for the special outings, Katy wore two equally chic looks that are easy to re-create. During the day, the singer styled this sweater-sleeved Free People denim jacket ($198) with neutral basics and a black Panama hat. Then at night, she channeled her inner glamour girl, working a floral sheath dress with yellow Charlotte Olympia ankle-strap pumps and a yellow chain-strap bag.
