The best thing is to dress well and taking care of your body and
care about your outer appearance.
Attraction is a very subjective. What is attractive to one person may not be to another. Don't rely on the opinions of others to determine how attractive you are. Instead, accept the person you are, and learn to present yourself in a manner that you feel good about. A complimentary hair style, clothes the fit well, and good hygiene are important. However, no one looks attractive without a smile. Be sure to wear yours often.
