What does the flower on the lady's hand do at the dance?

This is the tradition of American high school dance, which is equivalent to a rite of passage. Graduates in the last year of high school usually attend the prom. Sure, everyone can go. It's just a graduation rite. When a boy invites a girl to a dance, he will first inquire about the color of the girl's clothes, and then match them with his own evening dress color. In addition, the two sides also gave each other bouquets. What boys buy for girls is called a corsage, which they wear on their wrists. The girl named the boy a corsage, a kind of corsage pinned to his chest.
