Where should the boutonniere be worn?

The boutonniere should be worn on the left side and typically pinned to the left lapel of a suit jacket. This placement is traditional and serves a purpose: the left side is closest to the heart, which symbolizes love and affection, especially in formal occasions like weddings, proms, or other celebrations. Wearing the boutonniere on the left allows it to be prominently displayed while complementing the overall appearance of the individual.

The left lapel is a clear and recognizable spot, ensuring that the boutonniere is easily visible. This tradition helps create a stylish and coordinated look, which is why it is the standard practice in formal attire. The other options suggest alternative placements that do not adhere to this traditional guideline, making them less suitable for proper boutonniere etiquette.
