Elegant Gothic Lolita (EGL) is an off-shoot of Lolita fashion–style clothing popularized by Japanese musician and fashion designer Mana. Mana has his own EGL store, Moi-même-Moitié. It has branches in Shinjuku, Tokyo and Hiroshima, Japan as well as online through CDJapan.
It is commonly mistaken as the blanket term for Lolita fashion and Gothic Lolita in Western Lolita culture. The name "EGL" applies only to clothes in the Gothic Lolita style, not Lolita fashion in general. The different name reflects the prevalence of white, black, and dark colours in general common to goth fashion.
EGL makes up half of the Moi-même-Moitié fashion lines; the other half being EGA, or Elegant Gothic Aristocrat, which differs from EGL in that it is an androgynous line of fashion that caters to both sexes and is generally considered to be the more mature counterpart.
and Mana of course is in Malice Mizer:

keep an eye peeled on the runways and fashion magazines to see how its already deeply infiltrated western tastes with elements of the style if not outright full copies.
