Whoever said stay away from horizontal stripes wasn't speaking to Hollywood's current crop of rail-thin starlets.

French Connection's black-and-white striped dress has made the rounds among the California girls, starting with Olivia Wilde, who wore the graphic number to a store event for the retailer back in February.

The "House" hottie, who was recently voted sexiest actress of 2010 by Victoria's Secret, kept all eyes on the stripes, opting for natural makeup, untouched hair, and no jewelry.

Blonde reality stars, Paris Hilton and Stephanie Pratt, mimicked Wilde's simple but chic style -- both dressing up the casual T-shirt dress with sexy black pumps and super straight locks.

Hilton added extra accessories to her look -- shocker! -- including hoop earrings, a clutch, black tights, a headband, and black nails.

All three ladies definitely rocked the tight frock, but who wore it better? Vote now and then check out which celeb was recently spotted wearing a skimpy horizontally striped bikini.
