Most Helpful Girl
If the girl is legally an adult what really can you do? If she wants that type of attention, then so be it. If you are implying that she dresses revealing then this shows the level of her confidence. She is trying to compensate for something she feels she is lacking. I would sit down and talk with her, and let her know she can still dress sexy but age appropriate (we would go shopping together, and I would help her select some things). I would also tell her, not all attention is good attention.
