Can you be attracted to a girl who wears glasses? And if you are, do you think they look better when their hair is up in a ponytail or just down?

Glasses? Yes! Why not?
Hair up or down really depends.

Often it is the frame, some look better than others,
Glasses really makes no difference.

Hair up or down, depends on shape of face and how it is done.
Really it is the girl liking her own look, if she is happy with herself, her personality will shine though

Remove the glasses and look into the eye. Eye are window of soul.

I've worn glasses, not worn glasses, worn contacts, had my hair in a ponytail, had my hair down - I never took a poll but I don't anybody ever didn't like me or date me because of my glasses and/or hair.

My lenses were clear so I didn't have to take them off in order for someone to see my eyes.

Really it is the girl liking her own look, if she is happy with herself, her personality will shine though, I agree with this. You can wear lenses if glasses makes it difficult for you.
