What should I wear over my sleeveless dress? Shall, scarf?

It's hot pink with orange accents. Sparkles on the bust. Poofs out. Pretty formal. But like, party formal? If that makes sense lol. It's for 8th grade promotion so I need something to cover my shoulders since it's sleeveless. Do people wear scarves? Shalls? Anybody got any suggestions or pictures of ideas that would look nice? Thanks!
