Don't know if anyone else has heard about the new Marks and Spencer body shaper... oh my god.... the best buy ever! £28 and worth every penny. It basically a modern girdle... You can get them all different shapes to help pull in different parts. I went for the normal knicker but goes up to your bra... some have legs in and some stop at waist level... after having a c section my stomach muscles are battered... when i pull this body suit on i get an almost flat stomach, a waist and my bum lifts a good inch... I went for sz 14.. but in a few weeks i'm going back for sz 12... also i think it's helping the muscles go back...
