@daijokay I got curious about that and went back to check. the demon general only wore about 3 outfits? 1. a turtle neck + trench for outdoors. 2. standard long sleeve for indoors. 3. demon work clothes.
Based on that, I don't think it's a matter of good fashion sense but just too lazy to change into anything else and it just so happens it's fashionable? ^^"
