To use this bra and panty set, just put them on like you would with any other lingerie. Make sure to refer to the fit guide to find the right size for you. When it comes to maintenance, always hand wash the set in lukewarm water and then let it drip dry. Avoid using harsh detergents or bleach as they can damage the delicate lace and mesh. Also, store it in a cool, dry place away from direct sunlight to prevent fading.
