The uptown Prada store was out of jewel-toned shorts from the spring runway, but I tracked down a pair in the Soho flagship. After the aggressive shop clerk made me pull up my dress in front of everyone so she could guess my size, I was rewarded with divine pleated shorts. The royal-purple color would easily transition from a day in Prospect Park to a night at the Box. 575 Broadway, nr. Prince St.; 212-334-8888.
