Hollywood went all out with couture and floor-length frocks at this year's Venice Film Festival. Marisa Tomei, whom we always love, stunned in mustard Marios Schwab. We love that Madonna paired her butterfly-adorned Vionnet dress with matching red shades. Diana Kruger looked fantastic as usual in Chanel couture. Natasha Poly looked like she stepped right off the runway in that flowy Gucci number. And we may not know who Vittoria Puccini is, but we want to based on how elegant she looks in this Versace gown.
