Sheker hachein v’hevel hayofi is being misused here. It doesn’t mean looks shouldn’t be considered. It’s talking about what makes a woman praiseworthy. It says Isha yiras Hashem hi tishalal – she should be praised. A beautiful person doesn’t deserve praise for it. It’s not from them, it was a gift from Hashem. Praise Hashem for it, not the girl. The Yiras Hashem comes from the girl, and makes her worthy of praise.
That said, when a man is looking for a wife, he needs to find her attractive. Does that make her worthy of praise? No. It’s just a basic fact – a man should find his wife attractive. If he doesn’t, it can lead to serious problems down the road. Sheker hachein v’hevel hayofi refers to a person’s perception of it. Don’t try to exalt yourself because of it. It’s sheker v’hevel – it comes from Hashem, and Hashem can take it away whenever He wants to. Yiras Hashem is something that can’t be taken away from a person. But that doesn’t mean looks aren’t important!
