A trope where characters with a Limited Wardrobe or Memetic Outfit find themselves wearing far too little to possibly be comfortable (or healthy) given the current temperature -- but will usually not act any differently to how they do in other temperatures. Curiously, this is not as Unrealistic as its seems. In real life, there a sects of Monks who can control their own temperature and avoid frostbite (and sickness) even in bellow zero temperatures by (possible) mantras and at least one confirmed case (Wim Hof)of a man absolutely immune to the cold; this is of course exaggerated in fiction.
