Reese Witherspoon's simple bun may be a classic, but her front pouf adds an adorable touch. With added height on top, this style looks great on round face shapes.

Get her look: A day-old hair works best. To create the pouf, tease the front section of your hair, then pin back on top of the head using bobby pins. Next, pull the rest of the hair into a high ponytail and twist into a bun. Secure with bobby pins. Spritz all over with hairspray for hold.
