Linda Hamilton wide jaw
The famous Terminator actress is renown for her square jaw. Still, when you look carefully, the jaw isn't particularly square from the profile. A B minus at most. From the front the jaw angles are jutting because of well developed masseter muscle.
Her overall traits are massive. For reasons other than her jaw angle (nose, upper lip, skin...), I do not find her particularly feminine. There are women with much squarer jaws that are more feminine.
