It's the fanciest model-filled red carpet event of the year, the amfAR Gala, tonight in Cannes. And from actresses like Kristen Stewart to Victora's Secret models like Alessandra Ambrosio, the lovely ladies attending are wearing their evening finest—complete with many, many cutouts, sheer fabrics, and glittery embellishments. Here, all the best looks from the red carpet. Leonardo DiCaprio, a big fan of this event, may have stayed behind in New York City with his brunette model girlfriend this year, but fear not, the carpet is still full of naked dresses and eye-catching fashion.
