A suit is a set of matching garments, usually a jacket and trousers or a jacket and skirt. The pieces are cut from the same fabric and designed to be worn together. The suit is a formal staple, associated with business, weddings, and ceremonies. It has also been reinterpreted countless times, from punk suits to oversized streetwear versions.

Types vary. The single-breasted suit has one row of buttons and a centered closure. The double-breasted suit overlaps and has two rows of buttons. The two-piece suit is a jacket and trousers. The three-piece adds a waistcoat. The tuxedo is a formal evening suit, often with satin lapels. The morning suit is a formal daytime option with tails. The skirt suit pairs a jacket with a skirt. The trouser suit is a women's suit with trousers, historically significant as women entered professional spaces.

Fit is central. The shoulders should sit cleanly. The jacket should button without pulling. Sleeves should end at the wrist bone. Trousers should break slightly over the shoe. Fabric matters: wool is standard, with linen for summer and flannel for winter. Tailoring can adjust the fit. Off-the-rack suits rarely fit perfectly. Made-to-measure and bespoke options exist for those who want a precise fit. Care involves brushing, airing, and dry cleaning sparingly. A good suit can last for decades.
