I started as a size 16/18 at 14st 7 and 5ft6
I am now a size 10/12 at 9st7
Someone else on the forum may be built differently to me, and despite being the same height and weight, be in larger or smaller clothing sizes. Some people 'guesstimate' at a dress size per stone - but it really does depend on WHERE that stone comes from!
I have to agree with DebG that it depends where it comes from. My big tummy always held me at a higher size ... I had to wear at size 18 at 12st 7lb to fit over my tum even thuogh the shoulders, legs and bum were baggy. Had my weight been more evenly distributed then I may have reasonably been a 16.
BTW - I've just looked at your photos and you look like a different girl ! I hope I can nuster up your grit determination in a few months down the line
