To use the Black Kiki Thong, simply put it on like you would any regular thong. It's adjustable, so you can find the most comfortable fit for your body. When wearing it, you can choose to pair it with the matching Kiki Bra for a complete look or wear it on its own to show off your bold style. As for care, it's best to wash it by hand in cold water with a mild detergent. Avoid using harsh chemicals or bleach. After washing, gently squeeze out the water and lay it flat to dry. This will help maintain its shape and the quality of the fabric.
