Hard to believe that Kelly Osbourne used to come off like a foul-mouthed brat, isn't it? At last night's party for Flaunt magazine, the 24-year-old looked more like a punk debutante than an angsty teenager. While her hair may no longer be shocking pink, she still wears the hue with confidence on her lips. The exact color is MAC lipstick Show Orchid, a shade available only at MAC Pro stores. The key to pulling off a bold hue like this one? Stick with lipstick, not gloss, and keep the rest of your makeup simple. Cool.
