It is unlawful to wear a mask in public unless it is a holiday.

The Law Explained

Originally passed as an anti-Ku Klux Klan measure in the mid-20th century, this law prohibits adults from concealing their identities in public spaces using masks or hoods. While there are obvious exceptions for Halloween, theatrical productions, and recently, public health emergencies, the original intent was to prevent organized hate groups from terrorizing citizens anonymously.
