We mostly where second hand clothes, but sometimes we have clothing items that are still in great shape.  I like to send them to  Swap.com to be sold.  They take the pictures, you set the prices, they do all the interaction with the buyer and handle the shipping. They will even send a box or bag to you to ship your items to them.

They are very picky about what they sell. There are often times they reject something thatbI thought was in like new condition, but they found a small stain.  When buying, or swapping with them you know the items will be wonderful.
