My friends and I sometimes have clothing swaps...each season we bring items that we no longer wear in the hopes that someone else might use them. Clothes, shoes, bags, jewelry...we also bring home items.
It's a great way to walk away with something "new." And if something isn't your size and you're not afraid of a sewing machine (or your local tailor) alterations will cost much less than buying new.
All that's leftover gets donated to Goodwill, etc.
