These are just some speculations, based on what i know about the game, mythology, fantasy and history, so I can't 100% say if every i say is competly true.
The Outfit of the polar Fox Mommy and the other Foxes/Kitsune wear seem to be based on the traditional japanese Kimono.
While the others like polar Wolf mommy and the snow leopard mommy seem to be based on nothern clothes for warriors and adventurers.
I don't know about the earth elemental or the young owl girl.
If had to guess the earth elemental, seems purely build around the fantasy outfits for druids and Spirits. I didn't See the owl girls Outfit until, i guess it is going to be like a scribe Outfit.
