Mulberry know a thing or two about it bags. In the past 12 months, the Alexa has become the bag to be seen with, but now it faces a bit of competition. The Tillie (£812) landed in store last week and has already proved to be an enormous hit. The Spring collection includes this satchel with trompe l'oeil detailing which is available in several different colours. You voted for Mulberry as your favourite designer bags of 2010, but will they impress you in 2011 too?
