Why is it called a boutonniere?

The term "boutonniere" comes from the French Word "boutonnière," which means "buttonhole." Traditionally, a boutonniere is a small floral decoration worn in the buttonhole of a man's jacket, often for formal occasions such as weddings or proms. The practice dates back to the 16th century when flowers were worn to signify social status and to ward off bad luck. Today, it symbolizes elegance and personal style.
