To use this bra, simply put it on like you would any other bra. Make sure the underwire sits comfortably under your bust. When wearing it, note that it's best suited for lightweight clothing as it's designed to be invisible under them. For maintenance, hand - wash it in cold water with mild detergent. Avoid wringing it out to keep the shape of the padded cups. Let it air - dry away from direct sunlight. If you have any issues with the underwire or padding, contact our customer service.
