The criss-cross posture corrector bands in the back offer back support. Its open bust design lets you wear your own bra underneath, and it has a special design in the front to lightly center the bust. A 4-level front hook-and-eye closure lets you create the perfect fit. Plus, our seamless fabric won't show under your clothes.
