If you have a square face, a squre jawline then go for hats that are much more feminie, organic and prettier, so trims such as flowers and feathers, as these will help soften the severe jawline and draw your eye away. A low crown with a wide asymmetric brim would work well, but stick to those softer lines as much as possible and avoid srtuctured and geometic trims.
