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.
