Popular short hairstyles today include the bob. There are short, medium and longer (layers) versions of the bob style. See examples below. The shorter version of this style doesn't have many styling options, but the longer versions can be worn straight and smooth or all over curly.
As you can see in the photo below, Keira has a short hair style that features very long layering. This type of hair style will require frequent trims to keep the style looking good. Once those layers start growing out, they won't look as good and probably won't lay properly on the head.
Create this style on your own by applying a volumizing product throughout the hair and blow drying it with a large round brush. Direct all layers down and under, adding to the full look.
