Ashley Olsen Rocks LBD At Diane Von Furstenberg Dress Exhibition

There was some seriously good looks at Diane Von Furstenberg's exhibition launch in Los Angeles last night. Ashley Olsen pitched up at the event wearing a fab vintage-style LBD.

The twin went for an all-black ensemble and was wearing a buttoned-up and long-sleeved black frock.

The actress combined her frock with a pair of black heels and a little black tote. Simple, but chic!

Demi Moore opted for a glitzy black jumpsuit full of glittering embellishments.


But the winner of the best look had to go to Gwyneth Paltrow - wow!

Other stars at the event included Uma Thurman, Rosario Dawson and Iggy Izalea.

There was some amazing looks on display last night in Los Angeles... take a look!
