The eyes have power.
So enhance them, first of all. No, I'm not saying "wear as much raccoon makeup as freaking possible", I'm saying that you should do all you can to make them look their best! If that means makeup, so be it. If it means the right haircut, okay. Whatever it is, do it.
But most importantly..look people in the eye. I've found that not only is that a great turn on for guys, it makes them think you're confident, and it draws attention to how pretty your eyes really are! I can't tell you how many compliments I've gotten on either my "stunning eyes" or my confidence in maintaining eye contact. So far several guys have mentioned that they lose track of thoughts and time when looking directly into my eyes,
"it's like you're looking into my soul and everything goes blank."
I love my newfound eyes. :)
