Using these Kix'ies thigh - high stockings is easy. Just put them on like you would any other thigh - high stocking. Start from the foot and roll them up your leg until they reach your thigh. Make sure the silicone grip band sits comfortably around your thigh to keep them in place. When it comes to maintenance, it's best to hand - wash them in cold water with a mild detergent. Avoid using bleach or harsh chemicals as they can damage the material. After washing, gently squeeze out the excess water and lay them flat to dry. Don't wring them out, as this can distort the shape. Store them in a cool, dry place when not in use. As for sizing, always measure your height and thigh circumference as described. Remember, these thigh - highs are designed to fit women of all shapes and sizes, so don't be concerned about your weight. Just follow the measurement guidelines for the best fit.
