The band of a correct fitting knee high should stop about two finger widths below the crease of the knee. Most times if a stocking is uncomfortable at the knee, it is due to overstreching the fabric while pulling on the stockings. If this occurs, evenly redistribute the fabric downward on the leg using rubber gloves. There should be no wrinkles in the stockings. If redistributing the fabric does not solve the problem, you may need a petite or short size.
