Been a second-hand clothes junkie since I was 13/14 years old back in the States. Now it's just second nature as I love being able to get decent, unusual clothes for next to nothing. There are some people in this town who are really weird about it and think it's disgusting - but who is laughing when they compliment you on your clothes and you tell them you got them at Oxfam or PDSA? hahahaha we are.
I once got a City Lights Books tee for $1 at Goodwill .. and a pair of black 20 eyelet Doc Martens at Cats Protection for £5, brand new, my size. Those were my best finds ever, trans-Atlantic, and I don't have either one anymore :(
But now I treat ebay as a second-hand store and scour for oddities and bargains, and still get off my lazy butt sometimes and go into the charity shops in town. It's not something I ever intend to stop doing, even if I suddenly publish a novel and strike it rich. It recycles clothes that would otherwise be wasted / take up landfill space, if it's a charity-based shop it helps people or animals who need the money, you end up with clothes other people don't have [if you pay attention, some of them are quite old and no one has spotted that they are vintage and worth a lot more than £2!], and it saves our £s in a superficial society like ours where everyone wants our money. Can't be bad!
