Reduce, Reuse and Recycle Kid's Clothes

ThreadUp allows you to easily swap outgrown kids' outfits. In just a few minutes, you can pick out a box of gently-worn clothing that will fit your child, pay a few bucks to have the box shipped to you, and you received right-sized outfits. Then you put outgrown clothing into a free USPS box, write a general description of the box's content on the ThredUP site and wait for someone to request the box from you, which ThredUP arranges. And you don't pay anything to mail it out.

You can also create an "inner circle" of friends and family and keep your swaps within that group.
