We have all looked down at our left lapel at some point and thought 'why is there a button hole, with no button right there?" the answer is a lapel flower. Lapel flowers are coming back into style, so use them to your advantage. Match with a pocket square or tie, or both, just make sure the three don't clash, and don't go overboard. Show that you know what you're doing, without throwing it in everyone's faces.
