In all the world, วิบูลย์วรรณ (วิบูลย์วรรณ 
, Wibunwan ) is a very rare principally feminine, but scarcely male first name. The first name วิบูลย์วรรณ is characteristic of South-eastern Asia, particularly Thailand, where it is a very rare principally girly, but very infrequently male name. Very seldom, วิบูลย์วรรณ is the last name as well as the forename.
