It starts to rain

A few clouds started to approach above her, Harley took a look up at them but shrugged. "It'll be fine." And continued on, planning to have a lap around the park before heading home. She was a good distance around when a few drops of rain started to fall down and landed on her smudging the body paint. It became very obvious she was wearing body paint in just a few seconds but luckily for Harley it still covered more than if she was naked and picked up the pace and changed directions to get somewhere hidden.

People who saw her running got another good look at her backside before she ducked out of sight with the rain picking up and washing off the body paint in a few seconds and Harley then realised she was naked in the middle of Gotham park. "What the hell was I thinking?!" Her arms wrapped around herself and she made sure nobody saw where she was hiding which they did so she got out of that space and ran to hide somewhere else that could also keep her out of the rain.

An alley was the best choice for her at the moment, running in there and grabbing the lid off a rubbish bin to use as a shield from the rain. "Crap! What do I do now?!"
