It's tough to find a decent Vergil-esque coat that's either not a Mogstation item, not exclusive for males, or not a GARO thing, so this was the best alternative I could find. It's got some techno stuff on it, but oh well. You could substitute the gloves for Dhamelskin/Serpentskin Halfgloves of Crafting and the legs with High House Breeches, though the latter has some serious looking cameltoe...
