A swallow-tailed coat is a long, formal coat that has two pointed tails at the back, resembling the wings of a swallow bird. Other synonyms for swallow-tailed coat include tailcoat, dress coat, morning coat, cutaway coat, or tail-ensemble. Depending on the style and occasion, tailcoats can be single-breasted or double-breasted, with one or two buttons respectively. They are typically worn with matching trousers, waistcoat, a dress shirt, and a bow tie or cravat. Tailcoats are commonly worn for formal and semi-formal events, such as weddings, galas, and black-tie affairs. They are also popular among musicians and orchestra conductors, who wear them as part of their concert attire.
