i had ds2 a year ago and i am slim however i have a big belly still despite being at the gym! So for when im wearing skirts/want to look nice at the w/e's i want to buy some support pants. Are they actually anygood? I dont want whole body ones, just for my tummy. Are they not incredibly uncomfortable? Can you not see the very high 'waistband' that sits under your boobs?? Do you buy your normal size undies?
