NightLift is the Original bra and lingerie collection specifically designed to protect your breasts while you sleep. B.U.S.T. is the acronym for our exclusive patented Bilateral Uplift Support Technology, a revolutionary new construction system that lifts, separates and stabilizes the breasts so they don’t move while the wearer is lying down. B.U.S.T. is the structural feature shared by all NightLift sleep support lingerie. Developed by renowned plastic surgeon Randal Haworth, MD, FACS, NightLift is the first and only sleepwear collection specifically designed to protect the breasts and décolletage during sleep. It does this by helping prevent breast sagging and drooping over time by keeping the breasts perfectly immobile (but always in total comfort).
