I’m not too bent out of shape by it, because it’s just a goofy costume, and Nanook is some kind of spirit, so she probably doesn’t feel the cold. It just cracked me up.
Her appearance is pure Hollywood starlet--a body type almost unknown among the Inuit. In other words, she's your typical Native sex object. She comes from a long line of Native sex objects beginning with Malinche and Pocahontas. As well as a long line of Inuit women who supposedly gave themselves freely to men.
Compare her to Snowbird, a similar superhero who's a spirit woman of the north. No big breasts or exposed skin, yet still an effective character. If she weren't half Caucasian, she probably wouldn't be so statuesque, either.
