I don't think I really researched anything weird. Mostly weird things come up in my head about how things should go. One of which happens to be the discussion about how tails should work with pants.
My main character, Sauria, has a lizard-tail so it's really hard to reason with this. I even thought about slicing that thing up in the future but I feel like that would go too far in a very somewhat grounded story where trauma is very much brought up commonly.
My "solution" was to just leave it there and obscure her back side as much as possible. I'm sure some people would go "well put a hole in the pants and be done with it" but I'm not that simple.
