A double-breasted blazer is a type of jacket characterized by its overlapping front flaps and two parallel rows of buttons. This design creates a more structured and formal appearance compared to single-breasted blazers. Typically made from materials like wool or cotton, double-breasted blazers are often worn in professional settings or for formal occasions. The style originated in the 19th century and has been popularized by various fashion icons, including Giorgio Armani and Tom Ford. Double-breasted blazers can be paired with dress pants or jeans, making them versatile for both business and casual wear.
