I have noticed this trend recently and I think its appalling. I'm a bit disgusted to find bnai torah so concerned with how their friends will see their wives.
In my days it was good enough that a woman be a big baalas midos, a huge baalas chassed, a gargantuan machshiv torah, and most importantly to be her husbands biggest fan. Unfortunately, today eichah a woman like that is yushvuh buddud. The dor we live in is a terrible dor. In fact its the worst dor i ever lived in. I spit on this dor.
I am talking about bnai torah who seem more concerned about what their friends will think when they see their wife than whether she is the right person for THEM.
One can just imagine the thoughts going through his mind as he struts with his prize-winning wife out of yeshiva on shabbos morning:
"Look at me. Look who I am. I'm such a baal mussar. I've spent years toiling in torah, working on myself to get to this point. I think only of pnimius. I deserve a wife who everyone will look at and know that I will be the next gadol hador. I have got the fattest wife in town."
