Ok, so technically it is part of a costume and probably worn over actual underwear. Remember the Can-Can dancing Barclay Girls? I am finally getting around to cleaning and accessioning those costumes. These pink satin things were layered under lacy see-through black underpants. The flesh-tone underneath the black lace gave the illusion that the girls were more bare than they were, while still passing the censors.
And that, ladies and gentlemen, was a thing I vacuumed today.
