Bailey's Favourite Booty Band This Grippy Hip Circle ($25) from Mark Bell Sling Shot is a booty band that Bailey swears by. She said it has the perfect resistance and features rubber "grippies" on the inside (hence the name) that prevent the band from moving out of place. It also, she noted, won't snap.
