A "top hat" is a tall, cylindrical hat that is typically made of silk or felt. It is characterized by its flat crown and wide brim, and it is often associated with formal attire. The top hat became popular in the 19th century and is commonly worn at events such as weddings, galas, and other formal occasions. The top hat is often linked to the image of the gentleman and is frequently seen in theater performances, especially in productions set in the Victorian era. It is also a symbol of elegance and sophistication, making it a staple in the wardrobes of those attending high-society events.
