It's a throw-up between Nito and Medb.
I love both costumes, but imo Nito's artist always had this certain blurriness(?) to it that kinda bothers me. Or maybe I'm just going blind.
For Medb, well, it's just flatout appealing to the eyes. Like, damn girl, hate your guts, but work that pose. It's doing wonders for her. It's phone wallpaper worthy. If only the artist would draw more male servants like that....
