Because many of your portraits will be full-length, you should rehearse how you'll stand in front of the camera. It's a given that you keep your back straight and your shoulders back. But here's a trick that your mom may not have known (though Hollywood paparazzi do): Try angling your body 45 degrees away from the camera with your head turned to face it. "It gives you a more slender look," explains Gruber. "If you just stand there with your body square to the camera and look directly into the lens, it won't be as flattering." To enhance the effect, put one leg in front of the other, place your weight on your back foot, and point your front foot forward.
According to Newman, there's another way to cheat the lens, especially if you're wearing a sleeveless dress. "Don't hold your arms against your side -- the flesh tends to spread" and will make them look heavier, she says. "Hold them slightly away from your body." Of course, the shots of yourself that you love best of all might be the un-posed ones, in which case all you really need to do is smile -- and no bride needs to practice doing that.
