HAIRSTYLES FOR SQUARE FACES
Square faces tend to have a more defined forehead, so side-swept bangs are a great style to try. Loose, tousled bobs are also great because they soften your face. Any hairstyle that falls below the shoulders will help create length, and you can try going for an off-center part to give the illusion of a rounder face.
SUNGLASSES FOR SQUARE FACES
When you have a square face, you want to wear round/circular or oval frames to soften the strong jawline. Avoid angular frames as they accentuate your angular features, rather than having a complimentary effect on your face shape.
HATS FOR SQUARE FACES
For a square face shape, the goal is to wear hats that soften your angles. Hats such as fedoras clash with your strong jaw. To balance the angular width of your jaw, forehead, and cheekbones, go for a floppy hat with a long, soft brim. Beanies and berets also soften your angular features, especially the slouchy fits that show your hair toward the front of your face.
