I recently saw a really tasteful photo of a nude woman warpped in Christmas tree lights. It was very tasteful and you couldn't really see any "private" body parts.. but you can enough to make it R rated. She was posed perfectly and it was cool with the soft lights.

I tried to find it again but I lost the link !!!

Just an idea for you...

DISCLAIMER: BE CAREFUL WHEN YOU WRAP NUDE WOMAN IN CHRISTMAS TREE LIGHTS - SOUNDS FREEKING DANGEROUS !!!

Just some food for thought I wanted to toss out at you.
