You can just pin your curly hair up and have a great messy updo like Lauren Storm.
Setting your locks in rollers would help to get the foundation to get this look. Styling lotion or root lifter might be helpful too. Take pieces and twist and secure with bobby pins in random directions.
Pulling the length up and back and securing in a high ponytail will give the look of height. Just let the ends poke out every which way for a fun and sassy edge.
