I just bought a 'miraclesuit waist cincher' off ebay (though they sell them in DJ's..for $20 more) which is AWESOME! It's a corset....holds me in and I feel a whole lot better for it. Good back support and my stomach feels a whole lot better as my muscles are held in tight (my DRM is 3 fingers so my muscles need holding in!). Though I wear it backwards as all the hook things leave a line down my front otherwise if that makes sense?

I also have some killer undies (go right up to under my bbs) from Big W by 'Holdmetight' - they're also fantastic. Quite hard to get on but once they're on....holds my tummy right in and I feel more secure.
