If you are choosing something to make that special someone's eyes go pop- then make sure that you are going to be at an adult's only event or save that look for a private celebration. Do not scare little children and make the old guys reach for their medication. Do not wear a woman's fancy dress costume that leaves you freezing for the entire night. You want people to say, hey who is the good looking girl, not "hey what's with the blue girl in the corner?"
