Costume Contest Sponsorship

Soonercon is well known for its costume contests; bringing together some of the most talented cosplayers, sewists, and fabricators in the region. Our Saturday evening Masquerade Costume Contest is one of the highest-attended events of the convention weekend.

Costume Contest sponsors help us build reward packages for the winners of our esteemed competitions. And it puts your business in front of thousands of fans. We accept both in-kind (products, gift certificates, etc.) and monetary donations to bring our contests to life.
