I didn't have a white shirt so we used some white fabric and draped it around her shoulders like an open shirt. I used the shallow DoF 135/2L lens to hide anything again though she was also careful to make sure things weren't exposed (though the shadow makes it seem like it is).
Very nicely done to you both.
If you hadn't mentioned it, I would have thought it was a shirt.
A classy shot and Brandy looks comfortable with you.

David
