Sometime my theater let's actors buy their costumes after a show. This reason, and insurance, I give a listing to the theater of what is a faire replacement value on each costume an actor wears. (Could be $2, could be $200 depends on character)

Before our current show opened one guy asked he could buy his costume. I gave him the price I quoted the theater, $50. He thought I was jokeing. That much for a shirt and pants! He approached my trainnee to maybe make him a simular costume, after the show closed. "Igor" quoted him a price of $20 for the whole outfit including supplies.

After seeing me rebuild/remake other people's stuff that "igor" made after only wearing 4 wearing. He realized that the charge the theater was asking for his costume was actually reasonable given the quality. He tipped me a pint of beer for opening his eyes to this fact.
