There is a local spot that's kind of famous here in Reno called Junkee. Rather, it's kind of like two stores in one. The left side is retro/vintage/gently used awesome clothing and accessories. A lot of folks buy for Burning Man at junkees to give you kind of an idea of the variety of clothing you can find.
The right side of Junkee is like an antique store/junk shop/where you find weird and things. Yesterday a friend and I saw one of the sellers latest displays which is more like art. Freaking awesome. I love that store.
