In Skyrim most cloaks just outright remove your tail when modders add them, and I have to go back in and add my tail back. I pretend there's a slit up the middle and it's draping over the sides of it.
Only way it makes sense to me. it looks less odd than a khajiit or argonian missing their tails though.
Here? I'm dreading it, because the cloaks look weird.
