Oh. Em. Gee. We just died and went to fashion heaven! With Unknown starring two of our all time favourite stylistas, we knew that the press circuit for this new flick was going to provide us with LOTS of fashion fodder....but we didn't expect this! January Jones and Diane Kruger stepped out at the Hollywood premiere today, starting off their first round frock-off with a bang. January went for an über sleek, structured navy and gold embellished number from Alexander McQueen's Pre-Fall '11 line. Diane on the other hand opted for something more girly, in a white lace and crystal beaded mini dress from Dolce & Gabbana's S/S 2011 collection. All we can say is WOW. We're totally style-struck, so help us out and tell us what you think. Who looks more fab? Strong, sexy and streamlined January? Or flirty and super femme Diane?
