Beskap (Javanese: ꦧꦼꦱ꧀ꦏꦥ꧀, in Pegon: بسكَڤ borrowed from Dutch: beschaafd, meaning "civilised" or "polite") is a type of black plain jacket with a high standing collar worn by Javanese men on formal, official, or important occasions such as weddings. This upper-body garment was introduced in the late eighteenth century by the royal courts of Java and later spread to various regions influenced by Javanese culture. It is one of the principal elements of traditional Javanese dress, together with the blangkon.
Its front is asymmetrical, with buttons arranged diagonally rather than vertically. Depending on the type, the cut of the back may vary in length to accommodate the wearing of a kris, tucked into the waist. A beskap is always paired with a jarik, a long batik cloth wrapped around the lower body to cover the upper half of the legs.
