A bra is a garment designed and developed specifically to support the breasts. A bra may extend as far as the lower torso (as in longline bras or bustiers). However, undergarments that sculpt and shape other parts of the body in addition to the bosom (such as shaping slips or bodysuits) are rarely called bras. A bra, by definition, focuses primarily on the bust. A good bra can not only lift your bust, it can lift your spirits-alleviating back pain, evenly distributing the wight of your breasts, and even improving your posture.
