I measured my waist earlier and it's 29inches. I didn't measure my hips and I was in a hurry. I fit easily in a size 10 with room. Sometimes I am up to a 14 on top though (with shirts) as I am a 32e/f bra size.
I lost about a size per 1.3 - 1.5 stones. I was heavier than I looked though. I was a size 16 and very occasionally an 18 but was 15stone 9lbs and am now 10stone.
