The game looks great, though I'm not sure about 2B's outfit.
One could perhaps make a convoluted argument in defense of Bayonetta 2's 'sexier' optional outfits, for example, based on Bayonetta's persona, but 2B's outfit appears to be even more 'thong-like' than any of Bayonetta's, and the front slit of her outfit manages to give even normal camera angles a creepy 'upskirt' vibe. Also, 2B's blindfold (as well as the fact that she's apparently an android) would seem counter to any 'persona'/Bayonetta-type defense, but perhaps folks here more knowledgeable about the characterization in this series can weigh in on that.
I would just note that there's a certain threshold beyond which it becomes hard to ignore stuff like this, for some players.
Yea, it's not something that anyone would necessarily feel pressed to defend. At least, I wouldn't. But damn it all, I can't lie, I love her design; to me it feels a tad more stylish than something that's just blatantly sexualized as say, Cindy from FFXV. That being said, it's clearly a strong aspect of the design nonetheless (After all, everyone notices those thighs and panty shots), so I wouldn't blame anyone for not wanting to get the game (or having their interest in it greatly decrease) as a result of it.
