For those with a long face-shape, tall hat crowns that sit high on the head should be avoided, as they add too much height to the face and head area. Crowns should be deep enough to cover an ample portion of the forehead to even out the length of the face. Wide brims can be worn, especially ones that are turned downward.

Any hat with a medium-sized brim is perfect for someone with a heart-shaped face. The concern in this case is to balance out a wide forehead. If the brim is too large, the forehead will have an even wider appearance than normal. Other than that, this shape allows for a variety of different styles.

Square-jawed people are best suited for rounder hats that even out the cut, crisp lines of the face. Round and asymmetrical hats provide contrast to sharp jawlines.

Round faces work well with hats that have sharp lines and tall, decorative crowns thatare at least as wide as the face. Asymmetrical brims should be selected, or straight brims should be slanted to create attractive angles. These details all give great proportion and shape to a round face.

For the fortunate people who have an oval-shaped face, the options are virtually limitless. Most hat styles will suit this facial structure, so it's really just a matter of personal choice. Hats should generally be worn straight across the forehead or hairline.
