Alexa Chung must be a fan of contrasts: she's gone from the sublime Popworld to the ridiculously awful Get A Grip, and here at the Glamour awards she's paired an unflattering kids' party dress with a Marc Jacobs quilted Stam. Not sure where the dress is from, but you can get the bag at Net-a-Porter for £760.
