If you think you’re wearing the right size bra, you might be mistaken: most women aren’t! Wearing an unsupportive bra is not comfortable. What’s more, it can cause your breasts to sag and make you look heavier than you are.

To find a bra that’s slimming, look for a good fit—the band should be straight across your back. Start out a little firm: bras can stretch. Get a bunch of bras and rotate between them. Toss the stretched-out, broken bras, and keep the good ones clean. You’ll look five pounds slimmer!
