Costume parties and contests are a staple of festive celebrations, especially in lounges and nightclubs. While wearing costumes in casinos is generally allowed, certain restrictions apply. Masks of any kind, including eye masks, are prohibited, and face paint that obscures facial features beyond recognition is typically not allowed, even for those merely passing through. These rules help maintain a level of security and ensure all patrons are easily identifiable.

The evolution of costume traditions has a fascinating backstory. Take Let's Make a Deal, for example. When the show first aired, contestants dressed in suits and dresses—standard attire for the era. However, it didn’t take long for audience members to embrace a more creative approach, donning outrageous and unique costumes to stand out and increase their chances of being selected as a trader. This playful tradition quickly became a signature feature of the show, making it a cultural hallmark of audience participation and creativity.
