No matter what you call it—we’ve heard everything from ‘bingo arm’ to ‘bat wing’—arm jiggle is no joke. Get the last laugh with this scoop neck top, which slims the upper arm by up to ½” so you can wave without worry. Ribbed compression areas also smooth the entire torso, tackling everything from bra bulge to muffin top. Its longer length and lightweight yarn make it perfect for layering, but we love simply sporting it as a sleek tee, too. Nylon/spandex blend. Black or white. Sizes: S(2-6) M(8-10) L(12-14) XL(16-18)
