Opera Hat is a collapsible Top hat variant. Like a Tophat, an Opera hat is also a wide stiff-brimmed tall flat crown hat, worn on formal occasions. However, unlike the Tophat, the Opera hat has a spring system installed that makes the collapse possible.
Opera is made from black satin and has a grosgrain ribbon around the crown. A slight push on the top of the crown would collapse it flat, while a slight push in the opposite direction would snap it back up.
The opera hat is a formal hat that can be worn to classical music concerts, orchestra performances, and the opera. They are perfect for less spacious venues as they flatten much to be easily tucked away under the seat.
