For obvious reasons, today all the bags I've chosen celebrate London fashion. Starting off we have this messenger bag in Paul Smith's signature swirl print. Smith is a designer who's so 'London' he has his picture in the National Portrait Gallery. In a slightly ironic twist, the bag, from a designer known for his very British style and sense of humour, is on back-order in the US. If you're willing to wait, you can get it for $495 at Neiman Marcus.
