Corsage
A corsage is a small bouquet of flowers worn on a woman's dress or worn around her wrist to a formal occasion, traditionally purchased by the woman's date. Corsages are now most commonly seen at prom or similar events.
Originally named after the French word for the bodice of a dress to which it was attached, they were originally thought to be lucky or ward off evil spirits It has become a customary practice and a demonstration of affection from a date. It is thought that originally the gentleman would bring a gift of flowers for the parents of his date, and would select one flower to give to his date which would then be carried or attached to her clothing.
