Since her heydey in The OC, Mischa Barton has encountered some harsh criticism about her sartorial choices. So we were pleased to see the actress back on form at the Women for Women International Gala in London last night (3 May). Wearing a white Marilyn-Monroe esque pleated dress with cut-out detail, she wowed crowds on the red carpet. Shoe designer Charlotte Dellal and model Tali Lennox also brought some retro glamour to the gala with their outfits.
Meanwhile, over in New York, January Jones went for a bold printed Mary Katrantzou dress with peplum detail, to host a film screening.
