I do not advocate being stylish. That is equally silly. But to ignore the unpopularity of Yiras Hashem while attending to specifics of manner of dress is not the mission of yeshivos.
So you are saying, because the NYP didn’t have an article about the asei tov the yeshivah is doing to encourage Yiras Shomayim, they must be solely focused on the sur meyra.
The truth is that you don’t know. Fashion in Boro Park has reached a point that is beyond outrageous. Here is a Yeshivah that clearly can see this as an issue and are taking steps that will hopefully help their children in this issue. For all we know, the Yeshivah also incorporated mandatory lessons in a sefer about Yiras Hashem as part of their efforts. But that doesn’t make news in NYP.
Banning stylish clothes has its place (provided its not too little too late), but among the goyim it is also juicy news.
