Emily Blunt ballet question
I've seen this particular "move" often enough that I'm puzzled.
In this clip of her practicing her ballet, her one leg wiggles/wavers or whatever you want to call it.
What the hell is that all about? I do not know enough if every time I've seen it it was from the same ballet, or some signature move, but I figure since it's clearly intentional it must have some meaning or representation. Anyone know?
