I have a large frame. With 5% body fat, I would weigh 185lbs minimum, and wear a US size 14. I had size 11 feet until I had DS and they grew to a size 12 while I was pregnant. I have large hands, and moderate width fingers. I am 5'11" now, but used to be 1/2" taller.
I always scoff at the ads showing people dropping 10+ sizes on a plan with the "you can too" message. No, I wouldn't be living if I dropped that much weight.
