Whee! Did my exercises.

Can one of you americans reading this answer a question for me? How do US dress sizes compare to UK dress sizes? I know you use the same sorts of numbers but I'm pretty sure they differ - and I've read some stuff recently about women being 'size 2' which if it was UK sizes would be stick-women type of size. Ill and nearly dead. So I'm curious. To help, I'm a UK size 14 and I have a 30 inch waist and 40 inch hips ... what'd that make me in the US?
