To wear the Wonderbra Ultimate Plunge Bra, simply place the bra on and adjust the straps and back band to achieve a snug yet comfortable fit. Ensure the breasts are fully cupped and centered by the internal 'hands' for optimal lift and cleavage. For compatibility, this bra is specifically designed for outfits with deep plunging necklines. It is not designed to be worn strapless. For care, follow these instructions precisely: Hand wash only in cool water with a mild detergent. Do not machine wash. Do not bleach. Do not iron. Do not tumble dry, as the heat can damage the straps and rings. Gently squeeze out excess water and lay flat or hang to air dry.
