I'm just too lazy to attempt overly-frilly and impractical (and I don't think I could do it without a reference XD)! I feel like when I get to Grisia's drag outfit... it won't be fitting of his personality. I actually purposely drew Lesus' simple because he seems like a plain, practical guy!
Want to contribute to this 12 Holy Knights in drag?? HAHA We can make a list of who would wear practical clothes and who would wear frilly, fancy and split it up that way XDDD

(realistic is basically all I can do! what you see is the extent of my cartoon ability! It's quite sad)
