I'm a size 8 (I'm 5'2") so quite slim but certainly not toned. I have a belly but it's low down, a combination of a c-section overhang and a love of cake. I find that because I'm relatively slim, this belly part is really obvious and I'd love some control knickers that will pull it in. Any that I've tried seem to go up quite high and pull in further up iyswim? Is there a pair out there that will help control that lower part of a mum tum??
