9. Blake Lively

Sadly, she's not scheduled to attend this year, but, oh, what we'd give for a Blake Lively cameo. She kicked off last year's festival in an oxblood chiffon Gucci Premiere gown (not to mention one of the best black tie braids we've ever seen), then proceeded to churn out one killer designer look after another (see here, here and here) in the way only she can do. Someone buy this girl a ticket, stat!
