I love underwear as outerwear, no pants, leather tees and socks with sandals, but if there's one thing from SS10 I've been waiting for with particular impatience, it's Mulberry's Alexa bag. Alexa Chung carried a caramel version of her eponymous satchel throughout New York and London Fashion Week last September, and it's finally hitting stores this Monday, January 11th. Emma Hill designed the bag after spotting Alexa's vintage men's briefcase (also Mulberry) and added some girly touches and a handful of color options including snakeskin trimmed leather, hot pink leopard and a beige tweed - they all come in either regular or oversized. It's the first time I've caved to an "It Bag," but also the first time an "It Bag's" looked so classic. More images, after the jump.
