A founder or leader of a local chapter is usually referred to as a "Queen". Members 50 and over are called "Red Hatters" and wear red hats and purple attire to all functions. A woman under age 50 may also become a member, but she wears a pink hat and lavender attire to the society's events until reaching her 50th birthday. She is referred to as a “Pink Hatter.” During her birthday month (or the society's birthday month of April), a member might wear her colors in reverse, i.e., a purple or lavender hat and red or pink attire.
