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. Get a closer look at Katy's NYC styles, then shop her looks for yourself.
Penelope Cruz was spotted on the streets of San Sebastian, Spain looking ultrafeminine in this L'Wren Scott floral and lace sheath dress ($1,120, originally $2,240). The actress finished her ladylike look via black platform pumps and a pink leather clutch. Ladylike dresses have been all the rage among Hollywood's hottest — Eva Mendes is especially a fan — and we love that Penelope's number incorporates lace. It's a look that can just as easily work for the office as it can for a classy night out, but the most important elements are the fitted silhouette and knee-length hemline. Shop Penelope's exact dress and it will be a classic in your closet forever.
