A "Dinner Jacket" is a formal type of clothing typically worn by men for evening events. It is often black or midnight blue and features a satin or silk lapel. The jacket is usually paired with a white dress shirt, black bow tie, and formal trousers, creating a sophisticated look suitable for occasions like weddings, galas, or formal dinners.
The Dinner Jacket is also known as a tuxedo in some regions, particularly in the United States. It originated in the late 19th century and has since become a staple in formal wear. This attire is designed to convey elegance and is often required for black-tie events.
