I was thinking of using Amy's Blanket as a cape, seeing as how I remember it as having such a "blending color that'd match with just about anything"... But it just doesn't seem to match my transmog set (Acherus + Wrathful "Goatskull" Gladiator's Dreadplate Shoulders).
So I need help finding a cape that does... I'm thinking one that is long and black/dark, and has considerable heft/size to it. Nothing thin/dainty like the current pvp cloaks >_<
