blazer

A blazer is a type of jacket that is typically solid in color, tailored to the body, and designed with a clean, structured silhouette. Most blazers are single-breasted with two or three buttons, notch lapels, and patch or welt pockets. Materials range from wool and wool blends to cotton and linen, with velvet variants used for more formal or evening wear. Blazers are intended to be worn with non-matching trousers, distinguishing them from suit jackets; they are generally considered more formal than a casual sports jacket but less formal than a full suit.

The blazer originated in 19th-century Britain, associated with rowing and other clubs, and the name is linked to its bright, “blazing” color origins and naval affiliations. It gained popularity in British schools and clubs and later became a staple of American Ivy League and business-casual dressing in the 20th century. Today, blazers appear in professional environments, school uniforms, club attire, and smart-casual settings, with crests or embroidery common on organization or school versions.

Variants and construction can vary widely. Common forms are single-breasted with two or three buttons and notch or peak lapels; double-breasted versions exist as well. Pockets may be patch, flap, or welt, and back vents vary from none to center vents. Blazers can be lined or unlined, with fabrics appropriate for different seasons, including wool for year-round wear, cotton or linen for warmer weather, and velvet for formal occasions. Care typically involves dry cleaning or following fabric-specific instructions; ironing or steaming is used to maintain a crisp shape. Women’s blazers follow similar design principles with cuts adjusted for fit and proportion.
