Hollywood, as well as Washington, has gotten the Prabal Gurung bug. And it's easy to see why — his frocks are delicate, yet make quite a statement. Thandie Newton wore Prabal's black-and-white floral frock at the 2012 premiere. Leighton Meester went for a more daring floral frock. Demi Moore opted for a classy-cum-sassy Prabal at GQ's Gentlemen's Ball, and Michelle Obama wore the designer's sheath dress when she recently donated her inaugural ball gown to the Smithsonian. All breathtaking, but who wore Prabal Gurung best?
