Macabre. A quality of certain artistic or literary works, characterized by a grim or ghastly atmosphere. In these works, there is an emphasis on the details and symbols of death.
Macabre was an album and era of Japanese visual kei band Dir en Grey. There were many different outfits worn and many variatios of them but Kiba Tachikawa chose to make Die's most famous leather body suit. He says that the reason for this choice was for Hentai Katayama, the co-owner of Kanzen ni Jrock. His first experience with visual kei was Die in this very outfit.
