Thick, wide jawbones. Short, angular chin. A square face is the stereotypical “strong-jawed” look favored in classic Hollywood heroes, from John Wayne to Arnold Schwarzenegger to Tom Selleck, and even Johnny Cash. But while manly men of yore typically look like they can rock just about any scruff they want, they have some clear preferences that work best. You’re typically best served by going for narrow facial hair (like a goatee or a circle beard) because it lengthens your chin while accentuating your already considerable jaw. Square-jawed guys also look best with traditional mustaches—looking at you again, Selleck!—because their wide facial features can accommodate that grizzly upper lip.
Guastella’s pro tip for the aspiring Magnum P.I.: “If you’re gonna go for a mustache, go for a mustache. But keep an eye out for hairs that sort of cascade out into weird directions—trim them with small scissors to keep everything into an even, controlled shape. And don’t let the hairs go over your lip.”Back to top
