Nude while drying hands.

Stopped at rest stop to take a shit. I was only wearing a skirt, no t-shirt. It's a wrap-around with velcro closing. I fastened it loosely before exiting the stall. It stayed on while I was washing my hands, but fell to the floor as I was using the blower-type hand dryer. Waited until my hands were dry to pick up my skirt and fasten it more securely. No one came by while I was drying my hands.
