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 diamond face — cheekbones are the clear widest point; forehead and jaw are both notably narrower and close in width to each other. — the right hat shape can meaningfully rebalance the silhouette.
Construction and Fit
Construction: Curved brim, structured crown, sits high on the forehead just above the brow. Shortens the visible forehead and adds a straight horizontal brim line.
Why It Suits This Shape
Why it suits this shape: Soften and add visual width at the forehead and jaw to bring them closer to the cheekbone's width, while avoiding extra volume directly at cheekbone height, which is already the face's widest point. A baseball cap works well here because it's longer foreheads that benefit from being visually shortened, which is close to a direct description of a diamond face's starting proportions.
Where to Be Careful
Where to be careful: Faces already balanced or short in the forehead, where more shortening throws off proportion.
