Carrie showed up at the American Music Awards sporting a curled shoulder-length bob. Medium to long layers allows this hairstyle to bounce up to achieve body and fullness to this look. The top has been teased and pinned back for height and shape. This is a great hairdo for Oval, Oblong, Square, and Diamond face shapes.
