A story from one of my favorite sites out there, List of the Day:
In college, I worked in the theatre costume dept. as an elective. One day I ran across a rack of leisure suits, and the old guy that ran the shop told me a hysterical story.Apparently, he was a consultant to the Smithsonian on the preservation and restoration of historically significant clothing. He described the elaborate climate-controlled vaults in the bowels of the museum, with rack upon rack of cabinets, each with 6-inch high human-sized drawers. They carefully lay out the clothing on acid-free paper-lined cedar, to be preserved for the ages......except the leisure suits.Yes, the Smithsonian has a collection of leisure suits, as the costume trustees felt they were a significant fashion moment. But unlike all the other pieces in their collection, they have determined the 100% polyester suits are fine on wide hangars on a rack made of plumbing pipe. They estimated no measurable deterioration would occur for up to 500 years.
