I wonder if the 14 graphics engine can do something like this.

CookiesNCream is correct that the Western Market is a lot more sensitive about certain things than Japan is.

AnimaAnimus is also correct that China tends to be even more sensitive though incorrect in stating that game developers don't have to change things for the NA and EU markets. It's done a lot more often than people think.

The culprit isn't the players and what players will accept. It's the ratings board and retailers. A lot of retailers won't carry products that aren't approved for use by at least teens by the ratings boards. Each country's ratings boards has their own list of hang ups that will cause them to put a mature rating on a game instead of a teen rating.

YoshiP even went into a far amount of detail during an interview about some of the things they would like to do in cinematics and in game but can't because of the NA and EU ratings boards.

As for the OP's request, it's possible for SE to do. The question is how they would use the sheer appearance in gear models and if the ratings boards of any countries would have issues with it. It may not be a fight worth SE's time to battle since having such sheer appearances isn't necessary to the game.

Would you be happy if new content and features were delayed 3 months because SE tried to get something past the ratings boards and then had to redo everything when it didn't? Probably not. Better for them to take a more conservative approach they know the ratings boards will accept so they aren't forced to redo months of work at the last minute.

Guess what it is already rated teen and says partial nudity in the rating so what is the problem with outfit like this. No don't think it take 3 months it take same amount time because they still have to go thought them for any new content. Better look at the spring dress its kind of like this dress but open in the front so what make its worse adding mesh to open area of the dress.

Depends on the people who rate the game, I suppose. Yoshi-P has stated that they would have to re-release the game if the rating were to change for X reason (this was in regards to Rathalos' tail not breaking off as it does in Monster Hunter).
Australia's Classification Board would probably be the biggest hurdle, but that's just me being spiteful as they're a joke at this point (they were a bigger joke back in the days before we even had the equivalent of America's M rating).
