A maternity corset is a garment designed to support a pregnant woman's growing belly. It's also known as a belly band, pregnancy belt, or a prenatal cradle. The primary function of a maternity corset is to alleviate back pain, prevent stretch marks, and improve posture. Other synonyms for a maternity corset include pregnancy support belt, pregnancy belly band, maternity abdominal binder, and maternity support brace. Some women prefer to use a wrap or a girdle instead of a corset. However, a maternity corset is specifically designed to provide seamless support and comfort during pregnancy. Whatever term you use, the purpose of the garment remains the same: to provide relief and support to expectant mothers.
