Cupcake's Clothes have one, in a tan colour). I found one on a swedish site, called Talking Clothes, but that one was a bit expensive for me at £40! I found another one from a british webshop called Temporary Secretary for £18! In the end, I got my from Ebay for around £6! It's not the best of quality, but it's not a bag I'm going to use everyday, so I don't really mind that. Just a fun little thing.
