I live down the street to an amazing costume shop that often sells off the costumes it makes for local productions. I scored this awesome showgirl costume from A Funny Thing Happened on the Way to the Forum for about 20 bucks.
I think this will make a great bellydance costume with a little work. I especially love the sleeves which I'll keep for armbands. My spidey senses tell me there will be a trip to the Asian jewelry market for supplies in my near future.
