Where can you sell teenagers clothes?

My 16 year old has MANY abercrombie, hollister, and american eagle clothes. they are all in good quality, and not old at all. We went to plato's closet and they don't take kids clothing, most of her stuff is abercrombie kids. They didn't take a lot of the hollister stuff either though. Does anyone know of a good way to sell these clothes without getting ripped off??
