Not for sex. Just to remind them there's a standard to aim for. Insofar there's just French Pirate couple that pulls that off consistently in our region and few SCA Elizabethan veterans.
And its because the performers and workers aren't juiried or given a dress code or sold costumes that fit and are well made.
In the Midwest its rather like a child with no math or geometry skills did not even look at their own clothing or a skirt or blouse they owned and instead sewed 3 seams in a tube in a cheap shiny fabric they couldn't afford to buy more than three yards of, "gathered" it, then sewed a hem without measuring how tall they are so it drags into the ground.
THEN spends 200$ in real accessories from fair vendors.
This draws attention to the unfitted underwear corset bulging out the back 4 sizes too small with no lace protection, the droopy skirt with no petticoat, and to top it a 75$ hat worn with a modern hairstyle, modern piercings, no makeup, but glitter, and the tail of a dead animal hopefully tucked just into a pvc belt from Torrid. Which is cracking from strain.
Worn with PVC boots from Phantasma or a Amazon knock off which within 20 minutes causing blisters and foot damage. Or crocs. Like not even painted or disguised Crocs
And horns. And limp butterfly wings.
As somehow without a bonex bodice le tittes are everywhere. Up, down, all around. Under the chin. Resting on the knees, side boobing out the top wide armsceyes, or bound flat by a really tight bodice that didn't get a tuck.
No episode of Project Runway could prepare one for self taught seamstresses and amazon costumers.
And it has bled into college theater. 15000k granted fab labs and costume shops. And your actors appear as above?
