There are two bags I'm completely crazy about - Chanel's 2.55 and this one, the Mulberry's Alexa bag. I actually noticed that I'm crazy about bags recently.
Alexa by Mulberry is an improved Bayswater bag. The inspiration for it was Alexa Chung, I don't have to mention how much I like her style. You can get the bag in many different colours and patterns, but I like the dark brown one the best.
Also, I checked out a cheaper version. You can get it in Topshop.
