There are only a very few photographers on modelbase who is capable of setting up the lights, posing the model and accurately selecting the end product and processing it to a T...
Therefore step one... concentrate on getting the lights perfect... when you can achieve a shoot with perfect lighting then move to step 2.
view some proper fashion magazines or magazines showing examples of what you wanna photograph and make suggestions to the model. If you can achieve that then move to step 3.
If you are capable of selecting the outfit that fits the pose then make suggestions to the model.
Explain to the model why you like a photo and let her explain why she likes it / or not. You will typically find they look for way different things in a pic... start looking for the same thing, start recognizing the reason why certain angles dont work (ever) and why some angles will ALWAYS work.
Create the right mood for the model, play some music, suggest mood, dont be part of the mood.
If you can do all of the above then you are one of about 10 people on modelbase that I know that can do it.
1 mouth, 2 ears... and something about silence which might be golden...
