Her shirt, but it was torn and can sometimes expose Erica's privates.

Erica scrambled to put her shirt on, even though she noticed the large gashes on its side that sometimes gave flashes of her exposed (and fairly erect) nipples, it went down low enough to make it seem like Erica was just wearing a very short skirt or some really tiny shorts, but she couldn't bend over too much in it or risk exposing her very wet pussy.

Still, it was better than nothing, and now she had to think about what to do, she decided to...

• Head back to the dorm, she risks running into Lisa and her other friends, but that's where her clothes are.
• Head to the classrooms, they'll be empty by now, maybe she could find some jacket someone forgot.
• Head to the athletics hall, there are people there, but she's likely to find some spare sports clothes.
