Yep- check to see... if they are on a different day, there’s themes a lot now. I’ve worn sequined disco rompers, a practice dress with jewelry... heck, one time it was super hero themed and my teacher dressed as Thor and I was Wonder Woman.
Themed club nights seem to be how people are having more fun with comps and not taking them so seriously. A recent one in Cincinnati I think even did karaoke as a part of it.
But I’ve also done them in my regular rhythm dress when it’s on the same day.
What’s the comp you’re going to? Different organizers definitely bring different vibes to them.
