A couple of Sundays ago, I went to this Clothing Exchange just for women. It was on the other side of Daejeon, so it was a trek. I took several bags of clothes, shoes, and books.
You just laid your stuff out and then walked around the room, taking whatever you wanted. I thought it would be a lot bigger, but I did find a couple of shirts and books.
Since it's sometimes hard to find clothes that fit in Korea (we're not all size 2's and 4's), these clothing exchanges are wonderful. I wish we had them more often, but this was the first one I'd been to and unfortunately it will be my only one since they won't have another one for 6 more months. Bummer.
