Use stream of consciousness to answer the following. 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 designed to complement the dress or to add color to the couple, tying the whole look together. Prom couples may wish to go together to choose the flowers for a custom-made corsage or boutonniere. As time progressed, the tradition is that the male presents a corsage or nosegay to the female as a gift, while the female would get the boutonniere and pin it on the shirt or jacket. Typically for homecoming the corsage is used because it is a much smaller event compared to prom. For prom events the more modern choice is the nosegay because they are more appealing in pictures.
