Not necessarily. For some scenes maybe, but it's technically in the game for many situations. The typical one probably being the one where she's being surprised masturbating. I won't do a full tutorial, but there is the function Game_Actor.prototype.takeOffGlovesAndHat
in RemtairyKarryn.js
that pretty much does that. You'll want to basically call $gameActors.actor(ACTOR_KARRYN_ID).takeOffGlovesAndHat();
wherever you need it and test if it works (or the game crashes).
If it works, you're done. If it doesn't, you'll have to mess with the image files.
