A strapless bra is a type of undergarment designed to provide support without shoulder straps. It typically features a wider band and silicone or rubber lining along the edges to help it stay in place. Strapless bras are popular for wearing under off-the-shoulder tops, dresses, or any outfit where traditional straps would be visible. These bras come in various styles, including padded, unpadded, and push-up options, catering to different preferences and body types. Many women choose strapless bras for special occasions, as they offer a seamless look while still providing the necessary support for the bust.
