New and old look.
So obviously before you go insane you should look normal like a sane person would.
But then you should look different like messy hair maybe split lips. Cut on body even and you could have bags under your eyes and paler skin.
Maybe darker close to blend into the night instead of your normal clothes.
Soon after killing people you should start getting blood all over you and never brush or comb your hair as you will look more insane.
