Read Is My Bra Too Tight? on RealSimple.com.
Q: I always look like I have back fat. Is my bra too tight?
A: No, it’s actually too loose. A properly fitting bra is the key to a smooth back. Here are three strategies to prevent bra-induced bulge:
Make sure the band fits snugly (you should be able to slide only one finger underneath it) and sits low under your shoulder blades. “When the band is too large, the bra rides up in the back, which creates a roll,” says Lauren Amerine, a co-owner of Isabella Fine Lingerie, in Chicago. (Remember: The band should fit perfectly on the loosest hook, since the bra will inevitably stretch out.)
Look for a bra with a band that is wide under the arms and across the back to help hold in soft flesh (the closure should have a row of two or three hooks, not one hook).
