HI, there's a specialist boudior section on another forum I use, one trick I've noticed is if the subject is larger, they shoot in tight, so it's rarely a whole body shot, maybe they get up high and shoot head/shoulders/cleavage from above or a crop of the curve of the waist etc. it looks good but I dunno if I agree with totally hiding the size of the model instead of minimising, but a mix might be best.
heres a couple of boudoir shoots I like to give you some ideas,
