To use this bralette and thong set, just put them on like you would any other lingerie. When it comes to sizing, make sure to check the sizing tab above to find the best fit for you. As for care, always hand wash the set instead of using a washing machine to keep the fabric in good condition. After washing, let it drip dry rather than using a dryer, which can damage the material. Enjoy wearing this stylish and comfortable lingerie!
