I wear a lot of lightweight dresses in the summer and I feel my tummy sticks out. Apart from sit-ups, which I have started, is there a specific type of underwear you can suggest for holding in tummies.
You're in luck, there are loads of different support briefs that hold you in and give you a flatter, firmer look. The best thing is to visit a lingerie store and ask for advice. I have even taken my dresses in to try on just to be sure the underwear is giving me the look I'm after.
A few things to note:
*Don't buy your support briefs too tight. It's better to go up a size. If they're firm, your "excess" has to go somewhere so it sits either above the brief or where it ends on the legs; not such a hot look. And besides, you want to be comfortable.
*Look for briefs that have added grip at the waistband and legs to ensure they don't roll down/slide up when you move about or sit down.
*Support underwear is not something you wear everyday, so from a practical perspective, you might be best choosing a neutral colour that goes well under any garment.
In terms of dress style, avoid dresses that flare out at the waist (gathers, pleats, etc) - these can accentuate your tummy.
