36-33-39, 5'11", 11 stone 4 (or 158 lbs international-style)

I wear a size 42 suit jacket, but have a 38 bust
Funny you should say that, I buy much bigger men's jackets than my size requires, because I like a lot of cloth round me when I'm out in the hard cruel world. And similarly I find that with stretchy women's tops, a size 16 is right, but for anything that doesn't stretch or is supposed to hang elegantly, 18 is better.
