generally body language first, i'll see how they react to people and stuff. so i suppose face in general is where i start
then legs. i like legs
then hair because i can get a good read on hygiene/confidence/etc.
tbh i pay attention to what they're wearing and how it suits them more than anything
generally when i look at people i try to look more at their personality than anything haha
It varies. The most prominent thing is the eyes and hair.
And the butt, if I'm feeling shallow.
However, despite this being about liking someone physically, I find myself feeling less attracted to someone once I get to know them and their personality. Or more so, if they have a really nice personality.
