Sexy Halloween makeup

Hi everyone. I usually wear very natural, light makeup, just a little gloss, eyeshadow and mascara. Of course, this year I'm single and have a bunch of Halloween parties I'm going to that are going to rock. I'm going as a pirate (non-skanky) to the family-friendly ones and a freaking sexy dark fairy to the adult-only versions. Anyone have any advice on how to play up either look? Thanks!
