I remember the thrift stores in the US are full of second hand clothing that might as well have been all new or maybe worn once. And as a Dutch person I was amazed how much perfectly fine clothing was disposed of. Especially since I usually wear things till they break in some manner.
Actually there was a lot more well fitting clothing (mainly shirts) in the thrift places than in the actual clothing stores. Not to mention pants... for a Dutch person looking for pants in a US store is a no go apparently, it's all far to tiny...
