These crotchless lingerie sets are super easy to use. Just put them on like you would any other lingerie. When it comes to fit, make sure to refer to the sizing tab above so you get the right size. As for care, always hand wash them gently and let them drip dry. Avoid using harsh detergents or machine drying as this could damage the delicate fabric and the strappy back design. Keep them in a cool, dry place when not in use to maintain their quality.
