Firstly it depends what shop you buy your clothes from - size 16 in some shops is nearer 12/14 in others. But it also depends where you put your weight on. Women who carry it in all the right girly places can look amazing and curvaceous but women who put it all on round their middle (like me) can look really overweight if they only put on a few pounds. I'd give anything to have some curves in the right places!
A bit on the curvy side but it shows you enjoy yourself and aren't obsessed with being stick thin which causes you to be amnemic and all sorts as you don't get the right nutrients if you don't eat enough.
