Posted on FaceBook looking for volunteers to model for me for free and I give them the photos for free and some people agreed to that so I want to be prepared and at least take the right gear to the scene.
Here is what I have:

Lenses: 35mm, f1.8 , 85mm, f 1.8 and 24-70mm f2.8

and this type…full body length:
From here – may not be original source.
It is only 2 months I have owned my first camera so not too experienced but my thought was to take the 85mm f1.8 and put the camera on f 1.8 and focus on the person and shoot 
But what is your suggestions for taking shots like this based on the gear I have
