I too thought a 12 would be a total dream....so every size from there, down to the size 2-3 I am now, I bought too many clothes.....thinking there is no way I'd be smaller. Wow!
I never thought I'd no longer even be able to shop in a "regular" store for jeans or shorts.....for those I end up surrounded my teenagers. Or that when I do shop, I am at the OTHER end of the rack!
I never thought I'd wear a skirt that you can't really bend over in.
I never thought I would sit in a chair to tie my shoe and be able to bring my foot clear up onto the chair with me to do it.
I never thought I'd actually admit or notice the occasional guys watching me....and not to make fun.
