NY Fashion Week is looking like an episode of Wild Kingdom .... only with tortured, dead animals.

With NYC temps in the 20s ... the glam squad is breaking out expensive fur coats made of wild beasts --  sable, lynx, mink, fox.

Mary J. Blige ... Debra Messing ... Kenya Moore... Chrissy Teigen ... all offenders.

But with such cold temperatures ... it's not just about fashion --  just kidding ... yes, it is.
