A men's suit, usually a matching jacket and trousers, is a versatile garment for formal and casual events. The jacket often has notched lapels and buttoned sleeves, with single-breasted being common. Matched trousers sit at the waist, reaching the shoe tops. A waistcoat can add formality to a three-piece suit. Typically, suits are worn with a dress shirt and tie, but they can be less formal without a tie. The suit's fit is vital for a clean silhouette and comfort. They come in various colours and materials, with navy, grey, and black being popular. Suits symbolize sophistication and style.
