3. Watch your posture
Problem: Even a slightly hunched back visually shortens your neck and “adds” a few extra pounds around your waist.
Solution: Draw your shoulder blades closer together, and straighten your spine while bending backward at the waist. If you’re sitting down, don’t lean against the back of the chair. To make your body outline more defined, try sitting half-turned to the camera.
4. Change the angle
Problem: When you sit with your legs facing the camera, your silhouette looks bulky and box-like. Choosing the wrong angle can make your arms and legs appear shorter than they really are.
Solution: To fix this, you simply need to change the angle by slightly turning away from the camera. To keep your legs from blending together and make them seem longer and more slender, place one leg slightly above the other.
5. Turn your torso
Problem: If you turn your torso away from the camera too much your shoulders will appear round and narrow, while your waist will seem wide. On the other hand, turning your upper body toward the camera makes you look bulky.
Solution: The best option is to turn three-quarters toward the camera. This will make your waist look thinner and your bust bigger.
