To use this set, first put on the off - shoulder top for a stylish look. Then attach the stockings to the garters for a complete ensemble. Remember, this set is delicate, so always wash it by hand in cold water. Don't use harsh detergents as they might damage the fabric. When it comes to sizing, refer to the fit guide to ensure the best fit. And since the thong is not included, you can pair it with your favorite one.
