Sometimes what we don't see in a portrait is just as important to the composition as what we do see.  A silhouette is a perfect example.  Back lighting shows off this client's beautiful features, skin and hair.  This portrait has a private quality. It's sexy without nakedness or lingerie. 

If you Google image search "boudoir photography," you will see a lot of body parts, either naked or in lingerie, but few sexy portraits of individual women.  This silhouette photograph is both sexy and a beauty portrait. It is definitively HER portrait, not a collection of body parts. It's tasteful beauty and boudoir photography that can be framed and hung on the wall for all to see and appreciate.  It is the power of silhouette and the private mood of the photograph.
