Are idols mostly people who don't look like anyone else in their country?

maybe they were born with it

maybe it's maybelline PS

For example, someone like Itzy Yeji doesn't have any doppelgangers in Korea. And in general idols aren't just more attractive on average but also have looks that aren't common.

To answer your title, I think those two are basically the same thing. Truly beautiful people are rare. You could have an entire classroom and you may or may not find 1 handsome guy or pretty girl.

About Yeji, I think she is one of those rare cases even among rare cases as in her being rare even among beautiful people. She's just got a very unique and very beautiful face and body. Can't say for sure if she's had any plastic surgery done tho. Leaning towards no as I've seen her pre-debut pictures but you never know.

Prettiest girl in K-POP for me.

i dont agree, idols (and celebrities/influencers) look better than your average person because they live off their image, they spend the whole day taking care of their hari/face/body

obv there are the ones who are natural beauties but I'd say they're the minority, just like the naturally skinny idols

How would you know? Have you looked?
