Thanks! I really want players to be able to change outfits at their leisure, but it does mean having to draw several versions of every spanking scene, and that's the bit that's preventing me from doing it right now... In the code, it's all ready to go (and already works for the character sheet, for instance, where you will see these changes as the game progresses), but it's so much more work that I'm not sure it's feasible in any reasonable timeframe.
Having a different outfit for a one-off scene like the ball is totally doable, though; it's true that there haven't been many skirts in the game so far!
