Since getting the cat ears, I've wanted to make use of them properly, so I've looked into my own approaches into using them. Here's one of my attempts with making a look with heavy armor that'll work. I have done other heavy armor looks that look good with them, before that I may be doing soon ish if I'm not too busy. My so far favorite way to try for it is not too bulky of an armor where it may compliment feline dexterity better and movements.
Shortbow in those pictures is the Haunted Short Bow.
