So, we evolved to be attracted to people based on superior genes, or genes which, when combined with one’s own genes, would produce optimal offspring.

Now, aspects that you can change about yourself (fashion, creating a fake/new personality, working out etc.) don’t change your genetics. So people would have been evolutionarily hardwired to ignore these factors.

Of course, there are exceptions and ways to trick people into thinking you have better genes (pretending your personality is natural from your genetics and not developed), but that’s in spite of evolution, not because of it.
