Corsage

When attending a school formal or prom, providing a corsage for a prom date signifies consideration and generosity, as the corsage is meant to symbolize and honor the person wearing it. Corsages are usually worn around a prom date's wrist; alternatively, they may be pinned on her dress or a modified nosegay can be carried in her hand. The colors of the flowers are usually chosen to complement the dress or to add color to the couple, creating a unifying look. Prom couples may wish to go together to choose the flowers for a custom-made corsage or boutonnière. Traditionally, the male presents a corsage or nosegay to the female as a gift, while the female would provide the boutonnière and pin it on the male's shirt or jacket.
