Where should I be taking my lightly used, but no longer desired clothes? I try to clear out my closet once a year or so and eliminate anything that doesn't fit, doesn't reflect my current workplace dress, or isn't ever worn. I don't buy a lot of clothes, but there are still generally several shirts/pants/jackets (both outwear and dress) and shoes that I wish to pass on to someone.

I had thought My annual Goodwill drops were the best way to do that. What are the alternatives, especially that can contribute to my underserved neighbors?
