Depends on the community. In very yeshivish/chassidish communities, the “trophy” is yichus instead of looks (Rosh yeshiva’s daughter, einikle of this or that rebbe, etc). In other communities, the trophy wife is based on looks. This is an old practice, and used to be encouraged by the girls during their dances in the vineyards and orchards, according to the gemara in Tannis 25. The ones with the looks would advertise their looks, the the ones with the yichus would stress their yichus, and the ones with nothing would say “sheker hachein vehevel hayofi”.
