Cover up with the towel

(chapter originally by rojoa at writing.com)

The best option seems to be covering up. Isabel wants to get away from everyone so she can get dressed somewhere more private.

She lifts the towel to her chest and sits up. It would be difficult to wrap the towel around herself without showing more than she wants to, so she just holds it against herself with one arm across her shoulders and the other across her stomach, with the rest of the towel draped down.

As she starts to walk away, Isabel steps on the towel and nearly loses her grip, briefly flashing more cleavage than she'd like. She rolls up the towel with her hands to it's just tall enough to cover her breasts, and holds tight with both hands as she makes her way off the beach.

As she reaches the point where the beach crowd can no longer see her clearly, she catches her breath. Isabel is breathing hard, is embarrassed by her near-topless state and wonders how her relaxing time at the beach suddenly because so exciting. She starts to unroll the towel to get to her shirt and realizes it's no longer there...she must have dropped it when she left the beach.

What should she do next?
