Sometimes a little basic "polishing" and a proper mount are enough to transform historic clothing from tired, old clothing to artwork ready for display and appreciation. This 1940s dance costume underwent such a treatment.  Before treatment, on the unpadded mannequin, it hangs limp and creased.  After treatment, the costume is fresher and fits the mannequin properly, ready for a curtain call more than 60 years after it left the stage.
