If her right leg is bent, why doesn’t her coat stick out where her bent knee would be?

It’s not uncommon when having your hands in the pockets of an open long coat, that the garment is pulled forward, lessening the drape effect that would be expected with a slightly bent leg in this example.

Also, I’m looking at it a bit longer and it seems like a cutout of someone leaning against the wall with their leg up. Look how far forward her left leg is in the opening.
