Seriously guys don't worry about this kind of stuff, there is no perfect person. But if you want to get into it make yourself look good, get some nice clothes, do something cool with you hair, get a tan or even put make-up on and anybody can increase their attractiveness. Doing all that might sound a little gay so really just do whatever makes you feel more confident about yourself.
If your trying to get a girl realistically she's only going to be interested in your personality 'I'm in love with you for your personality, your looks are a bonus', so all you need is to have enough confidence to walk up to a girl and start chatting so she can find out just how awesome a person you are.
