Just add the nun outfit in postwork, like I did with my attempt at a “Blade” over there : https://epicgenerator.net/index.php/forum/chars/534-the-red-mage-s-characters?start=36#4182 🙂
Adding a full outfit is really easy and there are plenty of nun outfits over the internet, even though you bet you’ll find many of the kinky kind… 😛
