To use this wireless bra, simply put it on like you would any other bra. Make sure the straps are adjusted to a comfortable length and the cups fit well. As for care, you can hand - wash it in cold water with mild detergent. Avoid using bleach or harsh chemicals. After washing, gently squeeze out the excess water and lay it flat to dry. Don't wring it or hang it by the straps as it may cause the bra to lose its shape. Also, store it in a cool, dry place away from direct sunlight to keep it in good condition.
