A boutonnière is a single flower or arrangement of several small buds that is worn on the buttonhole of a coat or jacket. It is pinned to the left lapel, lower than the tie, but above the pocket square and should be angled towards the left shoulder.
Boutonnières are worn by the groom, groomsmen, ushers, and the bride and groom’s fathers.
Here’s how to pin one on:
1. Place the boutonniere on your left lapel, between your collar and pocket square, angled towards the left shoulder.
2. From the back of the lapel, pinch the fabric to envelope the stem (like holding a taco).
3. From the top down, use a long pin to secure the stem to the lapel, piercing through fabric, then the stem and back through the fabric again. Then you’re good to go!
