Looks cool, shines in the dark and, most importantly, has a side Minfilia-style butt-window which works great with the 2B leggings (no need for explanation).
The nutmeg coloured cloth in front does an amazing job at emphasizing the thighs while hiding the panties except when slightly looking from below (in which case you get what you want) - this way it looks really sexy while avoiding looking like a Lominsan s**t.
The jacket is quite rare, so you won't see people wearing the same stuff.
