The Sailor Animamates are made to wear lingerie-like outfits by Galaxia in a bid to assert her domination over them. The more “naked”, vulnerable or demoralised/humiliated they feel, the better for Galaxia to keep them humble and fearful of her. Kind of like a tyrant ruler who revels in humiliating those lesser than her by reminding them that they are essentially naked and thus powerless in her presence. Phi and Chi are allowed to cover up more of their body because they earned Galaxia’s respect to some degree.
