This shot of Lucy in my wife's 'borrowed' underwear illustrates my point.
The cups are obviously too big for her but I have tried to hide it (unconvincingly)
I guess I could have used the basque as a prop for her to hold but that would have left too little to the imagination, and that is part of the magic.
Have you ever used a wife or girl friends underwear for a shoot?
Did it fit your doll okay?
What did you have to do to make the photo work?
