If putting on your outer layer after cleaning it is anything like using a blanket or comforter out of the dryer, I'd be all over it.
I kinda reject the idea that the more human action is the more dignified action in general. If Momo prefers to have a shower, she should go ahead by all means, but if someone wanted to do something else they shouldn't be made to feel lesser, or feel like they contributing to others having an objectifying view of AI. If Clinton's exposed joints issue is the same for other robots, Momo is the only member of her support group who could even have a shower without having to fix issues afterwards.
Assuming they have the means to make the choice, I figure choosing an body like Momo's comes from a deep appreciation of the aesthetics of human life. And, at least in Momo's case, I believe the desire to do stuff in a human way also comes from that appreciation.
