Choosing Women's Wigs When selecting a wig that is suitable for women, you should be sure to select one that fits the shape of your face. Some wigs have a face-like shape However, there are some that are not as attractive. Using a tape measure to determine the length of one's hair would be great idea. A wig with a round portion will cause your facial appearance to appear larger than it actually is. Also, a short or cropped bob can make your ears look smaller.
