Chloe Sevigny

Also hitting the "Girls" red carpet -- and clashing with the busy backdrop -- was Chloe Sevigny, who sported a multi-colored minidress from Opening Ceremony, which she paired with clunky chain-adorned boots. The 37-year-old actress topped off her headache-inducing look with a messy matronly hairdo (and drop earrings), which aged her considerably. (4/4/2012)
