To use this lingerie set, simply put on the bra and panties like you would with any regular lingerie. Make sure the bra straps are adjusted properly for comfort and support. When it comes to washing, it's best to use a gentle cycle in the washing machine or hand - wash it with mild detergent. Avoid using bleach as it can damage the fabric. After washing, let it air dry instead of using a dryer to prevent shrinkage. Also, store it in a cool, dry place away from direct sunlight to keep the colors vibrant.
