A hat sits directly above the forehead, which makes it one of the fastest ways to change a face's apparent proportions without cutting or growing anything. On a square face — forehead, cheekbone, and jaw widths are nearly equal; face length is close to face width. — the right hat shape can meaningfully rebalance the silhouette.
Construction and Fit
Construction: Downward-sloping brim on all sides, soft unstructured crown. Softens the entire hairline with a continuous curved edge.
Why It Suits This Shape
Why it suits this shape: Soften the jaw's hard corner and add movement at the temples and chin. Rounded shapes — in a haircut's ends, in frame lenses, in a beard's edge — counter the squareness without erasing the jaw's natural strength, which most square-faced people are better served by softening than hiding. A bucket hat works well here because it's angular faces looking for an all-around softening effect, which is close to a direct description of a square face's starting proportions.
Where to Be Careful
Where to be careful: Already-round or soft faces, where the curve adds no useful contrast.
