If you have straight hair, you can create more width with bangs. Chin-length bobs and cuts are also ideal for you because they create the illusion of width. Curls & waves also add width, but avoid short layers that add volume on top. Bangs make your face appear shorter because they cover up a particularly large forehead. Shy away from blunt bangs & go for sides wept bangs like Hilary Duff (see picture).Extremely long or short cuts might look your face more elongate.
