1) A typical pair of sheer pantyhose lasts 1-2 wears. Generic pantyhose cost about $10, and name-brand pantyhose cost $25-35 (Commando/Spanx), designer pantyhose cost $60-$85(Wolford). So 50 wears in another pair of sheers would cost anywhere from $250 - $1500. When you look at it like that, our cost actually saves women money, not to mention frustration, over time.

2) Pantyhose are made with a pretty open weave, and are much lower denier than any shirt you would own, making them more susceptible to wear and tear - even when made out of an incredibly strong fiber like ours. But well taken care of - I'm sure they could last more than 50 wears. That said, it is an underwear product, so you may want to swap it out eventually :)
