Unlike any other robe in the game it has this really unnatural/curve around the back, it's really unappealing.

You can notice it even more when you sit down on a bench/chair. (this is the best way to replicate the problem and why I ask/request a change to the model). It's the only robe in the game with this problem so it can be fixed.
Thank you for taking item requests into consideration, appreciate it.
