Beauty's beauty. I don't know what's universal or not really. I've seen things people say is beautiful and I just shrug. I see some things as beautiful that others might just shake their head at. But there's likely some standards of beauty that are more-or-less universal. A lot is cultural of course too. Then again, I never found supermodels attractive even though I was supposed to. Seemed too dolled up to me, but maybe I'm just a nerd.
