Longer Lasting Pantyhose

Before wearing pantyhose for the first time, put them in the freezer overnight. First get the pantyhose wet, gently ring them out put them in the freezer overnight. Once frozen, pull them out slowly and hang to them to dry. Why does it work? I have no idea, but this tip has been around for ages and people swear by. You can also spray pantyhose lightly with a spray starch to help prevent runs.
