These tips are not for the skinny 90-60-90 girls but there isn't any word about the way to lose another couple of pounds. These tips will help you to look slimmer in front of the objective lens and feel more confident while being shot.
It isn't quite comfortable when the photo isn't a group one. In that case you have no one to hide your curves behind.
