A suit jacket is a formal piece of clothing typically worn as part of a suit. It is designed to be tailored and fitted, often featuring structured shoulders, a notched lapel, and a button closure. Suit jackets are usually made from materials like wool, cotton, or polyester, and they come in various colors and patterns, with navy and charcoal being popular choices. Suit jackets are commonly worn in professional settings, such as business meetings or formal events. They can be paired with dress pants and a dress shirt for a polished look. Accessories like ties and pocket squares can enhance the overall appearance, making the suit jacket a versatile wardrobe staple for both men and women.
