Even with minimal gear, the right combination of light, wardrobe, posing, camera settings, and post-processing can result in dramatic images that will make any woman look like a goddess bathed in soft, beautiful illumination.
1) Lighting: If I have a big white wall or background surface to work with, I will usually point a strobe directly at it in order to blast the area behind the subject with light.
When I only have a small flash unit to work with, I’ll put it on Manual mode and set the flash to 1/8 power or higher, depending on the aperture and ISO I’m working with. If you’re using more flash units, or higher powered strobes, you’ll have the luxury of smaller apertures and lower ISOs.
I’ll often place my flash at a distance somewhere between my subject and the background, out of frame, aimed toward the background at a 45 degree angle. There are other effective ways to bath your subject in background illumination.
The main idea is to hit your background with plenty of overpowering light, or use light AS the background. You don’t even need flash if you have enough constant or natural light to work with. For example, bright natural light coming in through a window just behind your subject might do the trick with the right camera settings.
Do you need a main light or some other type of illumination for the front/visible side of your subject? Some of that light will hit your subject on the camera side, too.

2) Wardrobe: Wardrobe is always a good place to experiment. But for this type of image, I’ve always preferred light and airy clothing and free-flowing hair. A light-colored, sheer fabric works great as a wrap-around. This type of lighting can also be flattering for nude subjects.
3) Camera Settings: Naturally, camera settings are going to vary widely based on the type, power, and positioning of the lighting. If your only real light source is coming in from behind the subject, the settings you use will determine the amount of overexposure you’ll achieve for the background, but it can also determine to what degree your subject will appear as silhouette. In a smaller room with lighter-colored walls, an overexposure of the background light will allow your subject to be more visible under the lesser illumination of the light scattering back to her from the walls.
With your camera set to Manual (“M”), you have an aperture of f/4, an ISO of 400 and shutter remaining constant at 1/250, you are successfully blowing-out just about all the detail in your background at your current background flash output settings.

Next, you place your subject in the frame to take a test shot which produces a silhouette with very little detail on the subject. Again, if using only flash, altering the shutter speed won’t be very helpful.
The latter, especially when shot with high ISO settings, can produce some intriguing texture because of the noise that becomes visible. Finally, I will often clone out distracting pieces of the background if it’s helpful to the final image.
