Yes

As she passed by the entrance to a small park, Amy saw an unoccupied bench not too far away.

"Ah, perfect!" she said before heading straight for it. She sat down on the bench and gingerly set down both her purse and the bag next to her. There were still plenty of people in the park, but she was a bit more isolated here than on the bustling sidewalk. Amy very carefully repositioned the dress, only having to expose her breasts for a split second while she regripped. Then she tied it securely in place, making sure to double-knot it this time.

"I guess I didn't tie it tight enough earlier." she muttered to herself. She blushed again at the thought of how many people had seen her back at the store. She couldn't believe that she'd had two brushes with public nudity in one morning! Amy was determined to get back to her apartment without flashing her goods any further! Amy stood up and resolutely strode out of the park.

But while Amy had been refastening the top of her dress, the ghost had been busy doing some refastening of its own. It had quietly frayed the bottom of the sundress, leaving it a tattered mess of loose threads. It then went about fastening those threads to as much of the bench as it possibly could. The result was slow but effective. Amy's flowery dress was unraveling from the bottom.

The farther she walked, the worse it got for her dress. Exiting the park, the dress had been shortened less than an inch. But soon that became over an inch shorter, then two inches shorter, and three inches shorter. Soon Amy's dress was barely even covering her ass! The ghost diligently kept up with its work as best it could. Whenever a thread would snap, it would re-affix it to a nearby fence post or streetlamp. If all the threads were holding, it would dislodge another one and get that unraveling too.

Amy was just one block away from her building and completely unaware of her worsening exposure. By now she was effectively bottomless and starting to notice people glancing her way. Amy's pulse quickened as she correctly assumed the worst. She glanced down, and to her horror saw her dress only came down to her hips, leaving her completely bottomless in public!

"NOO!! Not again!!" she shouted, desperately trying to cover both her pussy and ass with her hands. She had been ready to defend against any sudden gusts of wind, but certainly not for her dress disappearing on her! Amy took off running again, losing a sandal in the process of trying to get to her apartment as quickly as possible.

But this only helped to speed up the unraveling. Less than a minute later, Amy had reached the front of her building, and the rising hemline of the dress had reached the middle of her back. Unfortunately for Amy, that was as high as the dress came on her back. The last thread came away, and suddenly Amy's dwindling dress was nothing but a piece of fabric hanging from her neck. From the back, Amy was completely nude from head to toe, with just her hand partially obscuring her ass.

Having been waiting for this, the ghost moved into action again. It would've been a bit too difficult to undo the double-knot while Amy was sprinting, so the ghost just cut the string next to it instead. It had the same effect: the last remnant of the dress fell from Amy's neck, revealing her breasts to the world once more.

Amy grasped desperately for the tumbling scrap of fabric, but the ghost kept it out of her reach and quickly pushed it into the road. Amy hesitated for a moment before giving up and simply yanking the door to her building open. She stumbled inside, and continued running towards the elevator. Amy accidentally stepped out of her other sandal in her frantic sprint towards the closing doors, but she didn't dare turn around now. Her effort paid off and she managed to slide into the elevator just before they closed.

"Uh..." the man beside her in the elevator said.

Amy blushed deeply again as she scrambled to cover herself. She draped an arm across her breasts as best she could, with her other hand covering her womanhood once again.

"Just... uh... lost my dress..." Amy panted, trying to seem like it was no big deal that she was standing there completely naked. "Could you hit 5th floor please?"
