Played through the demo and I certainly enjoyed having her run around in just a towel!
The one thing I'm going to suggest is you have a bit of fun with the clothing system. Seems you can choose to have her wear whatever you want at all times, but the most disappointing and boring thing would be if the game didn't respond in any way to how you have her dressed.
What I suggest is that the dialogue changes based on what she wears. She should absolutely be commenting how she's just running around in a towel if you've got her dressed that way and she would definitely have something to say if you don't even have her wearing that!
More different dialogue for all the different kind of outfits you can find means more replayability. Especially if the game is good at having these sort of specialized dialogue whenever it can. Since there doesn't seem to be any voice acting that should make having lots of different specialized dialogue pretty easy to do.
