Men's suits are formal garments typically consisting of a jacket and trousers made from the same fabric. They are designed for various occasions, including business meetings, weddings, and other formal events. Suits come in different styles, such as two-piece and three-piece, with the latter including a vest. Common materials used for suits include wool, cotton, and polyester. The fit of a suit is crucial for a polished appearance, with options like slim fit, regular fit, and tailored fit available. Accessories such as ties, dress shirts, and dress shoes often complement suits, enhancing the overall look.
