You may covet your favorite celeb's hairstyle, but if the 'do doesn't fit your face shape, you're likely to be disappointed. Hence, Fabsugar's four-part series on the haircuts that best flatter your face. Welcome back to our fourth and final installment: square faces.

If you have a square-shaped face, you share your facial structure with Demi Moore, Mandy Moore, Sandra Bullock, and Rosario Dawson. Having a square face means that you have a wide hairline and an equally wide, angular jaw. The goal with a square face is to soften your hairline with cuts that incorporate bangs, layers, and your hair's natural texture.

It also means that you have lots of flexibility in the choosing which length you want to wear your hair. Almost any length is flattering. For example, you could try a long, sleek style with layers that start at the jawline and continue downward, like Demi's above. Or, you could just as easily go for a short and spiky cut with choppy ends.

Keep in mind that single-length bobs and straight-across bangs aren't great looks for you. They will just make your face look more square. Or, you can always throw in the towel altogether and opt for Demi's G.I. Jane buzzcut look.
