I just saw a wizard-as-fantastical-species shitpost and a maid-as-fantastical-species shitpost on my dash back to back, and now I'm kind of wondering what the maid equivalent of the classic "just a robe, a hat, and a pair of eyes" interpretation of the wizard-as-species would be.
(To be clear, what I'm asking is not "what would it look like if you put Orko in a maid dress"; I'm asking what it would look like if you constructed that type of extreme stylisation from first principles!)
I want to say something along the Fantasia route. If it's a species and not an item that's just brought to life, cats are supposed to be one of the cleanliest creatures. So, some form of feline, with a puffy fluffy tail to use as a duster. Cats are also already considered a liquid with how they can squeeze into things so take that a step further and now they can secreet cleaning fluids from their toe beans, making it easier to glide across a dirty floor and mop it. Possibly some sort of black and white long hair with the fur styled to look like a maids dress or butlers jacket.
