Rag o Rama is different from you average used clothing store in that they won't just take anything you bring them, and they can be picky in weird ways. I've seen K mart brand kids graphic tees on the racks in the same visit where they declined to buy stuff from last season at Urban Outfitters.
That said, they always have mannequins in the front window wearing killer outfits. The mens clothing section seems to be more reliable, while the womens, because they have so much variety, is more hit and miss. They also have a large selection of cheap sunglasses, belts, tights, and purses. I'd check it out if you're in the area or looking for something outrageous, but I wouldn't make a special trip there.
