I'm a belly dancer, crack a mean whip, and have a hobby as a historical costumer. All three have come into play. I had to teach an actress how to walk/sit/move, etc in a big, poufy, period skirt, teach an actor how to crack a whip (without just smacking it against the floor), and help another actor who wanted to change his posture for a character in a show where he played several different roles. We over exaggerated belly dance's base posture, and Bob's yer uncle!
