hey hun, i did exactly the same, lost over a stone and fit comfortably in size 10, i had 345cc overs from 34B and now 34E and i struggle with dresses and some tops, i need size 12 in some style of tops as 10s pull and look too tight.and in certain dresses a 10 wil fit great at the bottom, but wont fasten at the top, or pulls n looks too tight, its a pain in the arse! iv had to change my dress sense quite a bit. its gutting wen your just used to being a size 10! xx
