I need to invest in new control underwear to wear with my new dresses as I have a big tummy and love handles. I can't afford real Spanx so I'm buying some from ebay that I've had before but can't remember the size of.
Do I buy my dress size (18-20) or a size down (16-18)? Some say to buy a size down for maximum holding in potential but I don't know. If it makes a difference it's the ones that look like bicycle shorts that come right up under the bust.
