Marc Jacobs and his party posse were in London last night, celebrating his upcoming fragrance BANG, which launches here October 24. He managed to pull in quite the crowd: Jaime Winstone, Daisy Lowe, Beth Ditto and Jesus Luz. But all eyes were on Mischa Barton. Known for her sometimes, ahem, dishevelled appearance, the young actress looked smokin' thanks to killer blush and shadow application. It had a similar feel to January Jones' MET Gala look — the exaggerated block of colour — but Mischa also threw a classic winged eye in there, too. Interesting. But somehow it works. I love the whole rock 'n roll meets pretty girl vibe that's extended through her hair and makeup. Don't too? Or not so much?
