She has to go outside

Sue looked around the lobby for a way out, trying to ignore the cameras flashing from every direction routinely checking her invisibility. Almost immediately, she saw that the stairwell was blocked by a large group of reporters trying to get Ben's attention, there was no way she could get through them without bumping into someone. With the elevator broken, Sue searched for another option but all she could see was the exit which would do nothing but expose her to the whole world.

Thinking about the outside world, Sue remembered the fire escape on the outside of the building which she could climb to get over the reporters and back into the building. But it would mean going outside and risk being seen by total strangers could she really take that chance.

The choice was made for her when one of the reporters walked past her and she felt his hand graze her naked hip causing her to let out a small squeak. Luckily it only drew the attention of a few people who all lost interest when they didn't see anything, Sue didn't want to push her luck and made her way to the exit, keeping her distance from everyone and walking on her toes to avoid her bare feet slapping into the floor.

She was lucky enough to make it to the door, and after looking around to make sure no one would notice, pushed it open and stepped outside baring everything to the world. Even though she knew that she was invisible, Sue could stop herself from covering up as much of her body with her arms as she hurried into the alleyway where the fire escape was.

Trying to ignore how rough the ground was on her bare feet, Sue moved towards the ladder. Which is when she realised that it was hoisted a good 10 feet above the ground.

Sue internally started screaming at her misfortune before trying to grab the ladder by jumping, forcing her to stop covering her body. Unfortunately she didn't even come close and upon landing lost her footing and fell backwards on her ass.

By this point Sue was on the brink of tears as she sat naked in a dirty alleyway with no way to get back in. Sliding back towards the wall, Sue hugged her knees to her breasts in the hope of covering herself more and started to brainstorm more ideas.
