As Mattdm and Hugo made me realize I need new glasses Xo) I'm posting another answer.
Probably you can mask the light. I would construct a "masking box".
This image is just a panel, but it is the general idea.
Lets say you construct a pvc pipe box 2x2x.9 mts. (the .9 mts depends on the length of black cardboard you can find) and place it a little far from your softbox (or direct light), to mask the light in different specific points. This can be time-consuming but can be interesting.
If you have several heads you can use a very directional light to specific areas, using a snoot on each one.
I would also play with the clothing and posing. [1]: https://otake.com.mx/Foros/Masking-Box.png
