I want you to look in the mirror right now and remind yourself that you are beautiful. Because you absolutely are. And I promise that the men in your life know you are.
Fashion magazines try to sell a specific image - tall, thin and blonde - as the ideal of what beauty is. They chose that particular type and then sell advertising space to companies that make things that make you look like that type. It's disgusting and it in no way reflects what men find attractive.
Be proud of who you are and what you look like. Do things you love, wear what you want, and don't fear looking different than the yellow-haired stick figures on the magazines in the supermarket checkout line. You're fantastic precisely as you are.
