What is a "tailcoat"?

A tailcoat, also known as a morning coat, is a type of formal men's coat that is worn as part of a morning dress or black tie outfit. The tailcoat is characterized by its long, tapering tails at the back of the coat, which typically extend to the back of the knees. The front of the coat is cut away at an angle, revealing a waistcoat or cummerbund worn underneath. Tailcoats are typically made from wool or a wool blend, and may feature silk lapels and other decorative elements. They are designed to be worn with formal trousers, a dress shirt, and a tie, and are often paired with a top hat or other formal accessories. Tailcoats are typically reserved for very formal occasions, such as weddings, balls, or other black-tie events, and are a timeless and elegant option for any man looking to make a formal statement.
