Even Nintendo's Japanese division's director, Genki Yokota, talked about how all divisions of Nintendo communicate when making such changes.
“When we have costumes or clothes that we have a little concern with, we share it with NoE and NoA and they’ll say, ‘No, no, that’s fine’ or ‘You’re right, that’s an issue,’” Yokota said. “If it is an issue, we’ll go back and say we’ll say, ‘We adjusted it this way, what do you think?’ There’s a lot of back and forth in that sense. Rather than compromise, it’s like we’re all aiming for the same goal, of being able to provide a good experience for everybody in all regions. And we’re aiming to have a game that has very little difference between the regions.”

So does this mean that NoE and NoA think that Pyra's outfit and boobs are okay? Or maybe they still haven't decided if they will change her.
Edit: I want to clarify that I don't mind it if they leave her how she is, I just think it's weird that Nintendo thinks her outfit is okay.
