I am in need of slimming/supporting/wonderful undergarment I could buy for a wedding outfit? Just went around the shops today, but there are not a lot. AIBU to expect truthful reviews online? Sending back 3rd item today- when it says 'supportive' it has to be that- but not flimsy piece of cloth! I am large, need a lot of support (and even suck-in action!). Can anybody recommend any good body-mid thigh undergarment?
