Shinya from Dir en grey Visual Kei is a movement among Japanese musicians, characterized by the used of make up, elaborate hair style and flamboyant costumes, often, but not always, coupled with androgynous asthetics (For morons, lol, just kidding. :} Androgynous means refers to the mixing of masculine and feminine characteristics, as in fashion. Easy explaination for asthetic is the final outcome or look). But some sources state that visual kei refers to music genre or Japanese rock, with particular sound related to glam-rock, punk and metal.
These are what Visual Kei look like;
Alice Nine
Versailles
Believe it or not, all of them are guys even the one in the red dress? or whatever he is wearing. This style emergered in the late 1980s, pioneered by bands such as X Japan, D'enlanger, Buck-Tick and Color.
In my opinion, they all look like they are attending a dress party and a VERY, VERY posh one. :}
