Well done on your fabulous weight loss of 3 stone:happy096:
I would find that at the beginning it can take around the two to three stone to drop a dress size, but then as you come down it seems to settle into around a stone to a stone and half a dress size and the nearer to goal you get it does in most cases work out about a stone a dress size.
You will begin to tone up and shrink in inches...as well as losing your weight.
I really take issue with those tv shows that show those people who have lost two stone dropping up to four to six dress sizes
I've lost nearly 6 stone now and it's only the last stone and a half that seems to be shifting the sizes! It will happen, I promise I've gone from a 30/32 down to a 24 now, but it took ages to move down initially!!
