A couple of ideas;
1. Haver her wear a loose fitting robe for at least an hour prior to the shoot to remove any binding lines from her clothes and underthings.
2. Have her use a good skin moistureizer for about a week on her elbows, knees, throat and nect areas and on her lips to make sure that there are no dry skin areas.
3. If she is going to do her toes and fingernails, make sure they match.
4. If she needs to get any waxing done it should be at least a week prior to the shoot to make sure her skin is not red, same with the eyebrows and over her upper lip.
5. As for poses to reduce the stomach, make sure that she just arches her back as much as possible. (Don't say stick out your b**bs)
6. Don't let her rest her weight on her arms, it makes the tricep look too large. If she wants to do a leaning pose she has to use her abs to support her weight, not her arms.
7. Try to shoot her 45 degrees to the camera as much as possible and keep the camera height 1-1/2' over her head and shoot down on her slightly. The exception of course are 3/4 length and full length shots.
8. Try to ensure that she keeps eye contact with the camera, and use chin directions i.e. Chin up - chin down, tilt or turn her head using her left and her right.
9. Don't shoot every shot from the same side towards the camera.
10. For lighting keep it soft. Also you can use gauzy or real light materials to drape over parts she does not wish to show. Solid color scarfs that match her eyes or hair color work best.
I hope this helps,
Cheers,
