A term spawned by necessity on the superfuture style boards, then co-opted by 4chan’s /fa/shion board, “gothninja” addresses the current runway trend for draped, layered, top-heavy, grey and black urban battledress.

Unknown, possibly Rick Owens.
“Goth”, for the monochrome palette, overall gloom, Victorian and Edwardian inspiration,tattered edges, and super-tight, bordering-on-fetishistic fits. “Ninja”, for the obscured face, seaweed-like sweeps, and sense of sneakening.
The primary designers are Rick Owens, Gareth Pugh, and Ann Demuelemeester, the latter unpronounceable lady I just want to murder in her spooky bed for giving birth to these boots:

As it is not financially feasible to have these boots AND a college education, I suggest you youngins sit down for a good hard think about where your priorities lie.
Like asphalt Bedouins, the gothninja tribe wraps, drapes, and jangles. The look is prohibitive: only the extremely svelte (or starved) can really pull it off. The silhouette is stick legs and swooping shoulders, making this one of the very few nearly-non-unisex fashion statements. Lookbook superstar Biz C. pulls off some gothninja garb with applomb, but the lady is far from voluptuous.
Luckily (I guess), the signature drop-crotch harem pants sported by so many gothninja have appeared in outlets as accessible as H&M, where hipster scum are already pairing them with Wayfarers for the ultimate in street-level purgative effect. Just the other day I saw a group of them standing in a circle, affecting disaffection while playing some sort of hackysack/lacrosse mashup, cradling the ‘sack in their sagging trousers while rolling their eyes. I had to have a lie down.
This cunt remains ambivalent about the ol’ drop-crotch, but the rest of gothninja speaks to me on a spiritual, sexual level. I find myself wearing too many scarves, cinching here and draping there, and generally refusing to give it a rest. I am told regularly that I “look like a crazy person” and I just cannot bring myself to care.
And it’s not all black holes and revelations; a few rebel cels have splintered off to form new flocks.
