Not only is it crucial to wear pantyhose under your clothes to hide the bulge, but when you are in front of a camera, learn to pose properly. Always turn sideways to the camera with one foot in front of the other. Pull your head a little downwards to ensure that the double chin disappears. Hold your arm away from the body, and gently suck your stomach in. If you cannot do all this, then just look away from the camera, turn suddenly towards it with a smile for a fresh look.
