The Wonderbra Ultimate Strapless Bra is designed to be worn directly on the skin under any strapless garment. No special 'setup' is required beyond ensuring you have selected the correct size for an optimal and comfortable fit. It is universally compatible with virtually any strapless, off-the-shoulder, or wide-neckline outfit, making it a highly versatile addition to your wardrobe. For care, this bra must be hand washed only. To preserve the unique technology and materials, avoid using harsh detergents or bleach. After hand washing, gently squeeze out excess water and reshape the cups. Do not tumble dry the bra, as the heat can severely damage the straps, rings, and polycarbonate elements, leading to breakage and reduced efficacy. Instead, lay it flat or hang it to air dry away from direct heat or sunlight.
