can anyone tell me if they are generous or not? there is a lovely jacket on their website but i dont know whay size to orders. i am a 20 in evans and dorothy perkins, but in the sizing chart on simply be's site, my bust measurement means i should be ordering a 26!! and its not like i have a big bust, just a 42b!! if the sizes are around the same as evans, i will just order my usual size.
