Well, it won't be long before we have plenty of celebrity fashion to pour over. We're talking about Kim Kardashian and Kanye West's wedding, naturally!

But until then, let's tide ourselves over with some of the best looks of the week, shall we?

First up, all the knockout gowns from the Cannes Film Festival. Rosie Huntington-Whiteley opted for a bright yellow Pucci dress at the amfAR gala, and we just love the sunny results.

Then there was Alessandra Ambrosio, who also went for bold color at Roberto Cavalli's Annual Party Aboard. She looked so sultry in her electric coral Cavalli number.

And Marion Cotillard went for classic Cinderella style with a modern twist in a strapless pleated Dior gown.

And now on to the non-Cannes looks! Miranda Kerr stepped out to a Kora Organics event in Sydney looking so prim, proper and pretty in a silk organza Erdem dress.

And finally there was Bella Thorne, who upped her fashion game in a blush-colored Zac Posen gown at the LA premiere of Blended.

Now you decide who was the best dressed. Vote in the poll below!

Watch the Congrats Kim & Kanye Marathon all this weekend on E!, and don't forget Keeping Up With the Kardashians premieres Sunday, June 8, at 9 p.m.
