(Skin Concept) Lady Illaoi
so you know how the gentleman skin theme is a thing for some champs that are a little less civil? I'd say Illaoi fits right in for this theme, maybe even the first female champ to be a perfect candidate for it.
She could be wearing a flowing dress (not sure about the color) and one of those hats with a big and wide brim. She could be carrying around the top half of a Greek statue of a god instead of her idol. her tentacles could instead be giant arms and when the crash down they could make a fist.
You could even make this a legendary skin and give her a whole new set of dialogue like gentleman cho'gath has.
