She goes to class anyway

One thing Hermione would never do is miss class for any reason short of **** sickness, and thanks to the time-turner she had used in the third year, sometimes not even then. So although her skirt and jumper were dotted with holes, she pushed open the door and walked into the classroom.

Her desk was at the back, next to the window, so the first thing she did was grab the old wooden frame and pull on the window to close it. She got it to within an inch of being shut, but there it jammed. So close, but still plenty of room for more moths to get in, although thankfully she did not see any yet. She took out her textbook and sat at her desk.

"Oh, shoot." Hermione fingered the left thigh of her tights, which had laddered badly. "Can't blame the moths for that one."

She opened her book and tried to follow along with the use of runes as numeric signifiers to aid fortune telling, but was distracted by a fluttering of wings on her right sleeve. She brushed away the pair of moths she found there, in the process failing to notice a small group of them which had settled on her left shoulder. By the time she persuaded those moths to leave, the shoulder had been chewed through and Hermione watched horrified as her sleeve slid slowly down her arm, leaving the white cotton sleeve of her blouse.

She looked around, hoping no one would notice, and wondering how she would excuse have only one sleeve to her jumper. But that probably would not be what people focused on as she found holes chewed across both of her breasts, through the jumper and in places through her blouse to her pink bra as well.

"Ginny!" Hermione hissed to herself, "I've got to undo this curse."

Hermione examined her skirt and found it well-chewed as well, a ragged slit chewed from the hem right up her leg to the waistband. While she was examining this, she heard one of the Hufflepuff girls who shared the class exclaim,

"Oh, look, what a pretty moth! I think it likes you, Hermione."

Hermione tried to see which moth the girl was referring to, but it was difficult to tell as several more flew in through the window.

"Oh, look, there's more!" The girl added, as the new ones landed on Hermione. As fast as she flicked them away more were landing, and the ones she did get rid of circled around and came back for more.

"Oh my god, look what they're doing to her clothes!" A boy sitting in front of Hermione laughed, as the insects chewed through more and more of her outfit. They had rendered her jumper an unusable bundle of rags by now, and were making a decent start on her blouse.

"Please... I just want to finish this class and go!" Hermione pleaded, although it was unclear if she was addressing the admirers or the moths. A handful more moths were zipping in and out from under the desk, quickly turning her skirt into scraps.
