Well ain't that a tiny topic. 😁
I personally find very different people attractive. A wide variety. I like to think I have no personal preference, although trying too much with different enhancements is not usually attractive in my perseption. And I say usually because there might be a place for that too. You have to know when to wear an evening dress or fart pants. (Yeah, those are the only options. 😂 )
I think it's like what clothes you like. I like very different kind of clothes and think it's really interesting how people choose to clothe themselves. Everything is okay if you do it for the right reasons and that mainly is: what makes you feel happy and pleases your own eye. But if you're thinking that you should wear something or be something because other people around you say or are or the general perseption on what is beautiful determines, you're on the not so healthy path.
So perhaps being beautiful is feeling good in your own skin.
But having said that I do not think it's beautiful to be perfectly polished and symmetrical and without any "flaws". It's actually the flaws that make people look beautiful, so no to soulless AI generated ad/robot looks.
