The bra that Taylor Swift wore while training for her Eras tour! Only worn once, needed to size down 1 size. Please refer the website for sizing. The Power Bra by Forme® is an FDA-registered posture correcting bra engineered to immediately improve your posture, recovery, and upper body alignment for your best life. Most posture gear makes you dependent. Forme trains your muscles to do the work-naturally. Our patented wearables align your spine, speed recovery, and improve body awareness without limiting movement. Our best-selling posture bra is engineered with patented technology consisting of 6 varied tension fabrics and 8 powerful double-fabric panels, which together train your body to develop muscle memory that allows you to walk, sit, stand, and even sleep with great posture, breathe more deeply, and recover quickly without conscious effort. Designed by an orthopedic surgeon to help his mother battle poor posture and compressed lungs from cancer, Forme® will transform your whole body alignment, giving you posture that allows you to function, think, and live at your highest potential. For a more comfortable fit, stretch the armholes 10-20 times before wearing.
