FN size: 1X other stores: XL I wear a 38H bra and that’s where my weight carries. I wear a 12/14 in pants. I ordered a size up like the reviews said and I should have stuck with the 1x. while it fits my boobs, I have so much space in the body area. I like the dress but definitely have to get it taken it because paying for the return just to pay for shipping a new order for it would be about the same or half the cost but more trouble.
