Try to get one of the robes she owns in order

Hermione didn't say anything when she got to the entrance of Gryffindor Tower. She half-heartedly parted her labia for the Fat Lady so she could get into the Gryffindor common room.

Hermione went upstairs to her bedroom. Her mind didn't wander as she just began the needlework to adjust the hem of the dress.

Perhaps it was the mindlessness of the task, but she found it was going much faster this time.

After what had happened today, between Peeves making her lose a robe and telling the Slytherins, she decided that she didn't want Peeves involved in this any longer. While her heart may wish for the humiliation, she knew that she could get that in ways that didn't involve the poltergeist anymore. She didn't know if simply deciding that she didn't want it anymore would get the spell to work alone, however.

Hermione thought back to one of her first lessons in Hogwarts... A spell is composed of four things: wand movement, incantation, concentration, and intention.

Hermione threw the robe she was sewing to the side and stood up naked. While the spell that protected her wasn't her own, she grabbed a wand anyway to see what she could do. An incantation meant little, but she figured if she could say the words aloud of what she didn't want, Hogwarts might listen. She looked at the marauder's map to see where Peeves was. He happened to be outside the common room now. She sprinted down the steps and listened at the portrait hole.

"Grange-y, Grange-y, give me your panty doos!" He was singing. She heard a light giggle from the portrait, but she couldn't tell if it was The Fat Lady or Violet.

Stepping back into the common room, she raised her wand aloft. She concentrated as hard as she could with all the intention to ensure that her humiliation would come either at her own hand or the hands of the Slytherins. "I do not want Peeves stripping me anymore!"

... Did anything happen? She didn't feel anything. She went back to the portrait hole and heard nothing.

She ran upstairs to check the map and saw that Peeves was going away from the tower!

So... Unless she changed her mind, Peeves would no longer be an issue for her. She breathed a sigh of relief. She took a quick stock of what clothes she had left that she could wear... 9 borrowed robes, which she couldn't wear anything else with without being in serious trouble, 1 unfitting robe, and 1 robe that was almost done with alterations.

She went back to the needlework. About thirty minutes before dinner, she managed to complete the robe. She tried it on and found that it fit her well, even if it was somewhat shabby. She decided not to risk wearing this one to the entrance hall, however. She removed it in favor of another borrowed robe.

As she left the portrait hole, she decided to ask the Fat lady something. "Say... Was Peeves out here earlier?"

"As a matter of fact, he was." The Fat Lady confirmed. "He was all for stripping you naked again, but then he appeared to have changed his mind suddenly. He didn't say where he was going."

Well, that about proved Hermione's theory true. She couldn't say she didn't want to do the tasks, because then the spell would break, but she might be able to at least get rid of the ****... But it was just a question of how to do it...
