A celebration of London fashion wouldn't be complete without some mention of Matthew Williamson, so here's yet another of his fabulous 'Butterfly' diffusion designs as sold at Debenhams stores. The affordable range is the only way most mere mortals can afford his designs (I'm making quite a collection). This generously sized paisley bag is only £60, a far cry from the £500+ you'd pay for a bag from his mainline collection.
