A single-breasted suit features a coat with one row of buttons down the front, often ranging from one to four buttons, but most commonly with two or three. The design is sleek and versatile, making it suitable for both formal and semi-formal occasions. The jacket typically has a notch or peak lapel, and it may come with side vents, a center vent, or no vent at all. It often includes features such as flap or jetted pockets and a chest pocket for a pocket square. The single-breasted suit is characterized by its clean, streamlined look, emphasizing a modern and sophisticated silhouette that complements a wide range of body types.
