Shalom Harlow, the square jawed snow white
Shalow Harlow was a world class model of the glorious model period of the 90's. She was a top among the top. Her face is very wide. Lots of feminine facial fat, on top of a big, healthy face structure.
Chin is a perfect B. The vertical alignment between chin and lips is precise to the millimeter. Jaw angle is a solid B+. Cheekbones are also wide, accentuating the size of this big jaw box she has.
