Is there a cute guy or gal in your sights? Gather a few of your pals. Research shows that you look more attractive when you're standing next to two other people than you do solo.
Experts think it's because your features blend into an "ensemble" image, which makes any less attractive idiosyncrasies less noticeable! They call it the "cheerleader effect."
And it works both ways, too. Before you get that cutie pie's number, break him or her from their entourage to get a good look. (Wait - does a Twin count as two!?)
