on a more serious note, i feel that any pants worn by people with tails would have a hole specifically for the tail with a sort of button on the top for convenience. kind of like this?

at least thats how i think itd work.

alternatively i feel that meilius has worn normal people pants occasionally, and he wore them with the waistline below his tail so they were like. really low riding and practically hanging off of his ass. which leaves a lot of room for mishaps and is REALLY funny
