Functional fashion is the agenda for German designer Alice Kaiserworth, who has created a nifty two-in-one product called Dos Caras. One minute it's a sassy little jacket, the next it's a...erm, bag. What's even better is that everything you have stored in your pockets will remain there during the transformation, so no well-used tissues tumbling onto the pavement as you look around you in a state of sheer embarassment. It's great for the UK when the sudden change of weather from flood to searing heat requires an outfit alteration. Instead of lugging your jacket around trying to awkwardly drape it over one arm, you can simply morph it into its bag alter ego and away you go!
