Thanks for alerting me to those bugs! I've touched up all of them, and with the next patch of the game they should all be fixed up; although, in Wonder Woman's case, it will require a manual fix, but there'll be a little button in the clothing store to do that.
As for Luz; I agree, it looks better with them over the underwear. I'd never paid it much attention before, but that will be changed in the next update as well. Although, for clarity; they're leggings, not stockings, so they don't go all the way down.
For the maid outfit, what you're seeing is the upgraded maid costume that is currently only accessible in the Patrons-only version of the game. It isn't a bug- just hidden by a scene that you can't trigger yet.
Lastly, on the skin tone- probably not. I've considered it, because I get where you're coming from on matching certain wigs and accessories, but while the customization has never matched the cutscene images, I think Moana changing skin tones in transition to a cutscene would be a bit too jarring a jump. But maybe I'll add a way to adjust her accessories, so that they can shift to match better with her skin than vice versa.
