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!
