Dyed Clothes. Oh yes Definitely. My favourite latex catsuit in a dark purple 😮
The wardrobe. Most definitely as well. But, how about say Five presets. It would certainly save you from searching through all your clothes, when you could just press a button and be clothed as you want to be.
Changing clothes in room, Yeah why not.
Ball Gags. Absolutely needed.
Layers. Totally needed.
Longer dresses. A very long time ago I had a little chat with one of the Moderators on here about this. Apparently the Devs were looking into it but, nothing came of it.
Making clothes is tricky if you don't have the skills in Graphic Programs. Myself and quite a few others have looked and it gave me a headache.
So, yes some sort of a in-house clothing editor would be awesome as well.
