Designed to aid ‘out of whack’ lower backs, this under-the-bust bodysuit cranks up core strength, perks up posture and—hallelujah!—eases back pain. It uses sensory integration, which is a fancy way of saying it applies graduated compression that activates abdominal and lumbar muscles. Made with therapeutic, anti-microbial, temperature-regulating X-Static silver fiber, it’s seamless, comfy and discreet enough to don daily. Cotton/poly/elasthane blend. Nude. Sizes: XS(6-8) S(10-12) M(14-16).
