Dark web I reckon...mention they've been worn if you want max money
On a similar note (and sorry for being off-topic...) but someone put an advert on our local Freecycle page for ‘Hardcore’My mates girlfriend was a professional dancer until recently at which point she had a clear out of stuff she no longer needed. Being female she found things she’d never worn. She advertised a leotard on Facebook, “brand new with tags”. First reply: “Do you have a worn one?”. My mate and I nearly died laughing!
