Sims 4 University: Sim won't change out of Debate Clothes

I've recently had an issue in my game where I had my female sim, who is in university, participate in a debate showdown. She changed into that outfit/uniform and had the debate, but then she wouldn't change out of it once it was over. I tried to change her outfit manually, but all of them are the exact same thing; that debate uniform. I tried to have her shower, and nothing changed, she changed right back into that debate uniform when she was done. I entered CAS and in there, she has all of the outfits that I made for her, but in game, all she has are several copies of the exact same debate uniform. I also tried closing the Sims and opening it again, and nothing changed. Please help; I'd rather not have to have her wear that ugly outfit forever.
