1. Confidence is HOT. The male characters in Grease, mainly the T-birds and the Scorpions, were by-and-large not very attractive, but somehow they always had a flock of girls around them. That’s because they were confident; they were cool and they knew it…and girls love that. So be confident in yourself.
2. Changing your look can do wonders for you. In the final scene of Grease, Sandy ditched the poodle skirt and bell shaped haircut, and emerged in a hot monochromatic black on black look with a bad-ass hairstyle (for that time) and a whole new attitude. And everyone can agree new Sandy > old Sandra D. Try something new with your look and be confident in it. If you embrace your new look so will others.
3. Guys can and should dance! Nothing is more attractive than a guy who can dance so don’t be afraid to actually dance, rather than bump and grind, with a girl. Girls associate dancing with sex- if you’re good at the former, there is a high probability you’re good at the latter. Don’t know how to dance? Google it.
