I recently bought a DVD of an amazing dance troup called Georgian Legend. They do traditional Georgian dancing and their costumes are awesome! I immediately thought, those seem like something Folkwear would make a pattern for. So I emailed Folkwear my idea... and they said they're going to research it! I really can't believe it. I guess I figured they get requests like that all the time, but maybe not.
Here are a couple videos of Georgian Legend to check out. (Any of their videos are pretty awesome.)

Shows the girls costumes that I like. (bad quality video, but the best of the costumes I've found)
