Do you have gently used shoes or clothing that looked good in the store but were not so great when you tried them those first few times? How about that dress that is a bit snug, or the slacks you thought you would love and haven't worn for over a year? Comfort is what it is all about--if they aren't comply and make you feel great, pass em along.
Soles4Soles is a great non-profit organization. https://soles4souls.org They have partnered with ZapposForGood who will pay the cost of postage for your sending your gently used items to them. Go to http://www.zappos.com/zapposforgood/give and learn more. All you need to do is print out a prepaid UPS label, pack em up and drop off at any UPS store.
And, your gift is more closet space, and a wonderful feeling of having done good for someone else. Priceless.
