To use this lingerie set, first put on the bralette. Adjust the straps on the back to get the right fit. Then, slip on the thong and adjust the waist straps according to your comfort. When it comes to maintenance, always hand wash the set and let it drip dry. This will keep the fabric and lace in good condition. Remember, it's from Colombia and brought to you by Adore Lingerie. Always refer to the fit guide for the best sizing.
