My personal opinion is that the more revealing a photo gets, the more artistic I try to make it because I prefer to not just do nudity for the sake of nudity. Rather, I love it when it flows with the image and adds to the composition. I hear all the time, "I only want to do it if it's classy and tasteful." That's my preference too.
Precision in lighting and posing showing just enough to put the emphasis on the contours of the human figure.
Implied nude shots are where you are posed or angled or cropped in a way to hide any nudity.
Fabric, Furs, Sheer, Robes...
I have an embarrassingly large collection of silks and furs and fabrics and things to create an elegant goddess vibe.
