For a neat and chic formal ‘do, try a side chignon like Paris Hilton’s. Her hair is parted on the right, and all of her hair is swept into a smooth knot just below her right ear. Her bangs are left loose and styled to the side, likely using pomade for texture and staying power.
If your locks are short but you still want a thick bun, use a hairpiece or extensions that match your hair exactly. No one will know the difference.
Next, a flirty high ponytail.
