A lapel is the part of a jacket or coat that folds over the front. It's usually where you put your hands when you're wearing a dressy outfit.
You might notice that some jackets have buttons on their lapels, especially if they're made for formal events like weddings or business meetings. This is because the lapel can also be used as a place to pin a boutonniere - a small flower or decoration usually worn by men on special occasions. In fact, some people wear a tiny flag, badge, or even a miniature version of their favorite sports team's logo on their lapel. It's like adding a fun and personal touch to your outfit!
