A single-breasted blazer is a type of jacket characterized by a front that has one row of buttons and a narrow overlap of fabric. This design typically features a more fitted silhouette, making it a versatile choice for both formal and casual occasions. It can be worn with dress pants, jeans, or skirts, making it a staple in many wardrobes. The single-breasted style is often contrasted with a double-breasted blazer, which has two rows of buttons and a wider overlap. Common materials for single-breasted blazers include wool, cotton, and linen, allowing for various textures and styles suitable for different seasons and events.
