Guys, why would he let me see him checking me out?

I've been friends with this guy for a few years. A short time ago, we were at a party together and at one stage, he stood at the door and as soon as we made eye contact he stared for a few seconds, then checked me out from head to toe and smiled, all the while letting me see him do this. Why? He's normally a really shy guy so why would he suddenly be so confident and let me see that he was checking me out? Please help a girl.
