You can wear an iconic, versatile double-breasted blazer as a casual jacket with your favorite pair of jeans, or with a dressy suit to wear to work or a special event. This jacket design traditionally features two overlapping along with two parallel rows of buttons down the front. Most blazers have two or three pairs of buttons that form the rows, but many women's designs come with variations on the original style. These blazers come in many different materials, including wool, cotton, linen, velvet, corduroy, and synthetic fabrics like nylon and polyester. Men's blazers usually come in neutral colors like black, grey, navy, brown, and khaki, while designs for women tend to offer a wider variety of more vibrant colors and patterns. The blazers come in waist-length, which offer a more casual design, and hip-length, ideal for business attire, and the most common style of the jacket. Peruse the vast inventory on eBay to find the perfect double-breasted blazer to add to your wardrobe.
