Derech; I believe what derech is objecting too, is just that!
A Trophy Wife.
A Trophy wife does not mean a pretty or attractive wife,
or a super companion. A true trophy wife, means a wife who is chosen to show off with, more specifically in the physical appearance department, (what they call hot) is assur in every way.

2)Hatzneh leches
3)Me’od Me’od hevei shefal ruach,
4)one is knowingly choosing a woman who will be machshil
people by choosing a attractive partner for that reason so people will look and say wow, or think it, causing other to be Muchshal in Hirhur of Aishes Ish (If not worse R”L)
It might also cause shalom bayis problems for other people.
Maybe he’ll come home saying “why cant you dress like Shmoiger Bal Gaavas Wife?!” The Aishes Fas Poar! I mean Yefas Toar”
Not to mention all the Ayin Horahs!
Note; it is not assur to look for an attractive wife if it it what you want, need, or require, or all the above, just as long your reason is solely personal. Any obsessions based on her positive physical attributes in order to impress others, based on what others will say, is a big problem in middos, character, self esteem, and probably sanity. We are not goyim!
It always bothered me when guys ask like, what do they say in the street about her, is she pretty? without having their own opinion
on the matter, its sick! If you like the way she looks, great.
If you have no clue, then take whatever you like.
Don’t look for a spouse in order to please strangers.
If it’s not for your own personal desire, it’s just all the heartache without any benefits.
Nobody will like you more because you have an attractive wife,
They might act that way, (but believe me it’s not you they’re interested in) So why get yourself into all this trouble.
If not for practicality, then at least for the four reasons i listed above. If your not makpid on a gorgeous girl, be sensible,
besides not many girls are gorgeous, and those who are usually lean on that, while the others actually work on being gorgeous on the inside, and it shows on the outside as well if you look with the right set of eyes, yiddishe eyes that is.
