SaintEyn total derail but at 5' 7" and 59kg (9st 4) how are you a size 10? Surely you're an 8?
I'm 5'7" and currently 10st (63kg) and would love to be 9st 4 again as I used to be!
When I was though, I was definitely a size 8.... A 10 would have hung off me. I have 32D chest so not far off your size. Just thinking that maybe you are underestimating how slim you are at 5'7" and 9st 4lb!
