13. WORST: No Doubt, Gwen Stefani is a great fashion designer, but sometimes her personal choice of a la mode is questionable. The beautiful blonde stepped out in a sheer, bra-baring blouse and uber-baggy denim trousers, missing the al a mode mark completely. 15. BEST: Blake Lively looked uber sexy at the Chanel Resort 2012 Presentation in Atibes, rocking a black sequin jacket with an micro-mini tulip skirt and Christian Loboutin pumps.
