Probably about a 12. I think a 10 is unrealistic for me. I have HUGE boobs - always have had, since I was about 12 years old and an E cup. So I think to try and cram those into a size 10 is never going to happen.
So I think maybe a 12 on the bottom, 14 on the top is a realistic figure for me. But then of course it varies so much from shop to shop anyway doesn't it.
Slightly OT, but I went a bit mad shopping today because I'm now a very comfortable 18 rather than a reluctant size 20. And I was so excited that I can easily buy anything off the shelf in Next that i went a bit mad!!
pre-preg i was a 12-14 in tops, skirts and dresses, 14-16 in jeans and trousers. all boobs and bum. back to that would be great, not tummy, bingo wings and love handles like i am at the moment. i've kept all my lovely dresses, at the moment they're all very unloved sat in a suitcase in my loft. will hopefully be reunited with them one day lolol x
