Adding Tag

Hey, Im trying to add tag to the girl shirt.
I think im doing everything by the book, the area that im tracking is without blur or shadow and with solid pixels, i activate everything up to perspective and try to track the shirt. but i even dont close to figure it up
Anyone?

The hair is messing up your track. Also, her shirt is white with not a lot of texture. you might need holdout shapes for her hair and have a more complex shape that takes into account the area you are trying to track instead of her stomach to put something on her chest. Think of her chest as a plane and her stomach as a different plane.
