To use this lingerie set, simply put on the bra and panties like you would with any other lingerie. Make sure to choose the right size for maximum comfort. When it comes to maintenance, hand - wash it in cold water with mild detergent to keep the lace in good condition. Avoid using bleach or harsh chemicals as they can damage the fabric. Also, don't wring it out forcefully. Just gently press out the excess water and let it air dry. If you have any questions or concerns, feel free to reach out to our customer service.
