However, as the first president of Indonesia it was Sukarno that popularised peci — more precisely plain black velvet peci — as national men's cap of Indonesian,[8] and Indonesian male presidents have worn peci as part of their official presidential attire ever since. Indonesian official palace guards also wore peci as part of their uniform. The Paskibraka (Indonesian: pasukan pengibar bendera pusaka) or flag raising squad in Indonesian independence day ceremony also wear peci, and there is even female peci version with curved back.
