Camp being an important plot point in this episode, it is apt that Aria is wearing a tank top that she may have MADE at camp once, along with neon earrings that I BELIEVE are suede but just read like giant shoelaces. If she wears those at the next Teen Nick awards and tells people it's dried slime, she can avoid getting doused in the real thing. Although of course, my personal reference for this outfit is Brobee from Yo Gabba Gabba, if he were a teen in 1986.
