To use this lingerie set, simply put on the bra and adjust the straps for a perfect fit. The hook and eye closure on the back makes it easy to fasten. For the panty, put it on as you would a regular one and adjust the garters according to your preference. When it comes to maintenance, always hand wash the set and let it drip dry to keep it in good condition. Avoid using harsh detergents that could damage the delicate lace and fabric. And don't forget to refer to the fit guide to ensure the best fit for you.
