I'm ok with my partner doing what they want with themselves. But I would mourn good taste and style if the result was abysmal. But I know I have particular ideas about style elements. I'm picky. But everybody has an own taste. I like buzz cuts and blue hair but am less excited about the result of an explosion hair-wise. So, yeah, I'm bad at hiding things. When I cannot agree I'm silent and do not fake consent. But it would not be due to not letting me know, but due to choosing something ugly. If it's ugly.
