Taking a cue from Jessica Stam's fresh Summer party look, we're craving pieces with a decidedly preppy tilt, with unexpected accents. To start, shop for a neutral tank with the same body-conscious fit, then add a crisp, white tennis skirt. These basics will take you through season after season, but look fantastic styled up with feminine accessories, like Jessica's black lace platforms and antique gold clutch. With just her accessories, she added a big jolt of sexiness. Shop our picks below for the same chic play on party wear.
