Stickman unplugged. That's how I call it. And some stickwomen and another stickman dancing.
These following 3 bags might be very practical if you are fan of parties of any kind. I always hated to wear my bag when actually the only thing I want is dancing. With one bag on your shoulder it is quite difficult for me to concentrate on dancing. You can unbound your strap and fix the bag bands on your jeans or belt, so you have your hands free and nothing around your shoulder. You can move and dance freely.
