Not second hand now, but 'preloved'.
As you know I work in a retro clothing shop selling men's and ladies clothes, bags, shoes etc from the 1920's up till almost present day stuff. The owner of the shop makes a fair amount of money. I visit charity shops and see stuff that to me looks naff, but to others maybe not. Though i do pick up some tweed jackets that were probably 3 or 4 hundred quid maybe even more, for a fiver or a tenner at most! I also see certain underwear items for sale in charity shops. Who buys second hand underwear I ask.
Anyway, do you or would you buy someone's cast offs?🤔
