Long hairstyles with layers never go out of fashion and add lot of volume and character to a hair style. You can experiment with severe layers to soft layers depending on the look you want to achieve. Adding strategic highlights also improves the overall look of the person. They work well with all face shapes.
Long layers all around works well for someone with fine hair as it will add shape around the face but the back will have volume. You can also keep the long layers and add side swept bangs as a touch of style. Chin length layers work well for anyone who has thick hair. Short layers all over, medium layers with curls can be tried as well.
