I once saw an article about how to make money on line and this was one of the ways to do it - worn knickers, socks and tights
apparently eBay don’t want to encourage people to sell this type of stuff and so have a rule that any clothing for sale has to be listed as washed/clean/new for it to be allowed. There’s some sort of coded wording that fetish types know about - one of them is ‘freshen up’.
I know I sound like I know far too much about all this but I swear haven’t sold (or bought!) anything like this myself - honest to god, not even messing.
