There is a swap place down my way that is run by church. Each bag of clothes is worth 10 points. You then do your "shopping" using those points.

I really like the concept. That way you are not looking for a direct swap of anything, nor do you have to deal with the other swapper. All the clothing is sorted before swapping, so there is no issue with clothes being dirty, worn out etc, as they are sorted out and given to the charities that make rags.
