Choosing Women's Wigs If you are choosing a wig for women, you should be sure to select the style that is compatible with your face shape. Most wigs designed for women have facial shapes, but some are not as appealing. Using a tape measure to gauge the length of your hair is a good idea. A wig that is rounded part can cause your facial appearance to appear wider than it really is. Also, a short, cropped bob will make your ears look smaller.
