The purpose of the study is to revaluate the new artistic values of Suprematism that immensely influenced the Russian culture in the beginning of the 20th century. Also through studying the relationship between people and costume within works of Malevich, who wanted to portray humanity through his art works, this study will research on how Suprematism not just stood as Russian Avant-garde art but significantly contributed to art and costume expression. The study methods are as follows. First, consider the formative background of Suprematism style of arts. Second, study of the development of Suprematism art through both Suprematism art and Non-objective art. Third, study how Suprematism style of arts is portrayed in art costume through works of Malevich. The results of the study are as follows. The Russian Suprematism art costume strictly originated from the Russian Suprematism style of arts. Suprematism simplified any reproductive element of fine art with a creative energy, which reflects the statement of Malevich that said, "The object does not exist, it only stands as a symbol." In other words, Suprematism abolished ordinary response to basic environment, and created a much more serious reality than the innate reality of the environment. When applied to art costume, such style sought after geometrical simplicity in shape and Neo-Premitivism trait in color. This trend is also expressed in 21st century fashion in new forms of Minimalism or Futurism. In this respect, Suprematism still holds an artistic value in a novel form even after a century since the beginning of 20th century when Malevich first presented Suprematism.
