What is a "dinner jacket"?

A dinner jacket, also known as a tuxedo jacket or a black tie jacket, is a formal jacket traditionally worn for evening events and occasions that require black tie attire. Dinner jackets are typically made of high-quality materials, such as wool or silk, and have a tailored and fitted silhouette with satin or grosgrain lapels, buttons, and pocket trims. They often have a single button or no buttons at all and can come in a range of colors, although black is the most traditional option. Dinner jackets are typically worn with matching trousers, a dress shirt, and a bow tie, and can be paired with a cummerbund or a waistcoat for added formality. They are an essential component of any formal wardrobe and are a classic and timeless option for any elegant occasion.
