I would stick to using cute decorative bra's and bustie's with some padding with thong bottoms to show her hips and waist. Also, one good trick for the model is to lean forward a bit, cause's the illusion of having more up top!
Do not shoot her full body profile nor directly, but always at some angles.
Looking forward to seeing the outcome!!

I am doing the lean forward thing in this shot.
