"You are beautiful."
If only there were a way to say it without sounding corny, a way to make you believe her, then your best friend would tell you this. It does not—repeat does not—matter if you agree. It does not matter if society's skewed perceptions of the female body concur. It does not matter what the rest of the world thinks. You know this about your friends, and they know it about you—it's like crowdsourced good self-esteem! You are beautiful, and your imperfections are, to the people who love you, part of your charm. After all, who knows your true beauty if not the people who love you?
