I don't know. It could be anything, and our perceptions are different.
Some like famous people- celebrities, from sports, film, TV or other spheres. But I am talking of mere mortals here. What makes the guy/girl next door, or those from the Ordinary Mortals class attractive?
There are probably many things. These might also be surprising in some cases.
Sincerity or honesty in my view, is one major factor that makes a guy/girl attractive.
A helpful nature.
Intelligence, in some cases, if it's not tinged with arrogance.
Sense of humour.
Politeness of demeanour.
A good smile helps, in all the above..
The opposite, what makes people unattractive, in my view at least -
Arrogance
A tendency to show off..
Zero respect for other people's time.
Inability to smile.
Inability to laugh at oneself.
