How many flowers are typically used in a boutonniere?

A boutonniere typically consists of one flower. This single flower is often complemented by greenery or additional elements like small accents or fillers, but the main component is one focal flower. This design keeps the boutonniere simple and elegant, making it easier to pin onto a suit lapel without overwhelming the overall look. Historically, a single bloom has been traditionally favored to maintain a sophisticated appearance for formal occasions, such as weddings or proms. Using one flower also helps to highlight the specific choice of bloom, allowing for personal expression and coordination with the rest of the outfit.
