Johnnie Brock's Dungeon Party Warehouse offers the biggest selection of adult and children's costumes, costume accessories, make-up, hats, wigs, masks, shoes, boas, tights, everyday and Halloween party supplies, props, special effects and lighting in the St Louis and surrounding areas. Johnnie Brock's also offers thousands of adult rental costumes. Locally owned, Johnnie Brock's is a landmark in St. Louis and has been in operation for more than 75 years. This place is a hidden gem and is considered the "costume spot" in the central Midwest. Customers can find any type of costume imaginable, and the store is so big that one might need to leave breadcrumbs to find their way around. The prices are fair, and the costumes, mascot outfits, and inflatables are pretty great. The cat and employees are also highlighted as the highlights of the store.
