The Cannes International Film Festival is a key date in the calendar for fashionistas everywhere to see what Hollywood's elite are choosing to don for the red carpet. But which celebrities rocked the red carpet and which ones should have stayed back in Beverly Hills... Coming in at number three we have Gwen Stefani. Now Ms Stefani is known for her edgy, and sometimes bizarre, dress sense but this time she played it relatively safe with a floor length L.A.M.B gown that she wore to the amfAR'S Cinema Against Aids Gala at the Hotel Du Cap. This classic dress does encompass everything about Cannes, it's elegant, feminine with just a hint of drama, but we can't help feeling that Gwen would have pulled something more special out of the bag for one of the biggest fashion events of the year! Maybe next time... At the other end of the scale we have South African model Candice Boucher who attended the premier of Hearat Shulayim wearing this very daring, and somewhat revealing, dress. Now everyone here at LBD HQ knows that models need to make an entrance, but surely there is a better way than donning something which would fit in perfectly on a night out in Newcastle rather than on the red carpet? Fashion fail! Finally we have Uma Thurman. Now even though Uma has resorted to yet another Dolce and Gabbanna number, this dress is extremely elegant and looks simply stunning on Uma Thurman's figure. However, Uma doesn't escape that easily as this isn't the first time we've spotted Uma Thurman rocking this dress (she wore the exact same outfit to the Late Night with Jimmy Fallon Show!). Oh well at least Uma's proving that when you can always call upon your faithful little black dress!
