Where can I get funky plus size clothes in England?

I'm an American ex-pat, and in the states, there are places like Torrid, where you can get plus size clothes that aren't dowdy and boring, but it seems harder to find things like that in England. Even if the clothes are a cute design or pattern, they're so oversized, as if all plus sized women want to be covered head to toe! I'm going to Bluewater this week and I want to find some shops that have cool and different stuff. Thanks!
