I've definitely got birthdays on the brain as I've been daydreaming about handbags that I can't afford :)
My favourite is probably the Givenchy - I love the chain and the clasp detailing.
If you're in need of a quick fix but can't justify the bag, the (slightly more affordable) matching cuff is available at Harrods.
Clockwise from left: Givenchy, Wang, Proenza and Chanel.
