Donate. I tried the sell thing, to help bring in some extra cash and the effort to get it all together, photograph it, post on eBay, monitor the auctions, ship it if it EVEN sold, just wasn't worth the time while trying to take care of my family, do school, etc...
Tried Craig's List, too. Didn't even try consignment shops after the pennies on the dollar they offered for nice, nice clothing.
I would much rather give it away to someone I know who needs it. Sometimes it's not about the money...
