EEEK! Sadie hawkins dance coming up and what do i do?!?!?

Im in 7th grade and Friday 13th my school is holding a sadie hawkins dance for just the 7th and 8th grade. I'm not asking any guys but i want to look the best anyway. What do I wear??? Its casual and i was thinking of of a denim mini skirt with this zebra top i have but i want something new and fresh! Links are really helpful
