Her looking like a famous glamor pin-up was supposed to be an immediate clue. First, her clothing and manner are very very dated, indicating that Polaris is isealizing, he is doing what some drag queens do, trying to recreate his ultimate, and slightly cartoonish in this case, idea of femininity.
Which he got from a combination of his nightmarish, but attractive aunt, and the light bondage pin-ups of his youth, the time of his trauma, and the time of his sexual awakening.
And finally, he chooses a bondage queen because he himself feels powerless and a hostage to his fears. Polaris could be one of THE most dangerous DC villains, easily, he could be Magneto. But his personality flaws keep him a b-lister.
