Using these Kix'ies Ally Black Polka Dot Thigh High Stockings is easy. First, measure your height and thigh circumference to find the right size. Then, simply roll them up your legs. The silicone grip band will keep them in place. When you're wearing them, you don't have to worry about them slipping down, whether you're sitting at work or out having fun. As for maintenance, it's best to hand - wash them in cold water with a mild detergent. Avoid using bleach or harsh chemicals. After washing, gently squeeze out the excess water and lay them flat to dry. Don't hang them up as this might stretch them out. With proper care, these stockings will last you a long time.
