Malgosia Bela, polish square jawed model
Malgosia Bela has my favorite jawline type: the concave jawline. All jawlines have some sort of concaveness if you strip them from tissues, but on some women, chin and jaw angles are so developed that the jawline does no longer appear round or flat.... it seems concave.
Look at her upturned chin, and massive jaw angle: this creates a concave bending where they reunite. Exquisite isn't it?!
