I don't know, maybe some kind of "summer camp" clothing pack. Summer is getting closer and closer but this is my random guess. They might make the counselor's clothing pack that is closer from the first movie of the counselors in the first few scenes.
This is just my random guess, I doubt they're going to do it but I just thought of it for fun.
BTW! I've been following this "trope" for a little bit and it's where I definitely belong but I didn't make my account yet. I just made it yesterday and I'm excited to be a part of the "mean girl" trope. I'm super excited about Melissa being in the game soon and based on what some people said, she won't be coming to the next update??? It bummed me out but I'm still kind of hoping they WILL put her in the game next update.
