Brand New with Tags Forme Power Bra in Obsidian Black - NEVER BEEN WORN - PRICE IS FIRM. I just bought this a month ago, and it's too small for my chest, but I missed the return window, which is only 21 days for Forme. The Forme Power Bra is the most popular posture-correcting bra, engineered to immediately improve your posture in real-time for better health and confidence. The Power Bra by Forme is an FDA-registered posture-correcting bra designed to improve posture, support recovery, and enhance everyday wellness. Engineered for everyday movement, it activates key muscle groups and naturally guides your body into proper alignment—without discomfort or restriction. Powered by patented technology featuring six tension fabrics and eight double-layered panels, it helps build muscle memory, allowing you to move, breathe, and recover with ease. Developed by an orthopedic surgeon for his mother, who battled late-stage cancer and suffered from poor posture and compressed lungs, Forme® transforms your body by building a foundation that enables you to perform, think, and live at your highest potential.
