FDA Approved for posture correction and back/neck pain. Taylor Swift put these on the map, but I’ve been wearing them for years and THEY WORK!! Check out their site for all the benefits and correct sizing, as you want a snug fit. I ordered a M for my daughter to try and she really needs a S, but unfortunately she wore it a few times before deciding the sizing wasn’t right and it’s too small for me. So this is a bargain!!! Actual pics represent color better than stock photo. Smoke free home.
