Denevre looks like she has a full body suit too. And.. Ugh. What's her name. The one who's weak and whiny.
I don't see why they'd need many changes of clothes. Since they don't need to eat or drink much, it's not like their clothes would get dirty through sweat and soiling. Plus, it's not like they even need clothes to protect themselves from the elements, and armor is useless considering their opponents.
Logically. They should all just run around in bikinis. Or naked.
