Boudoir, relax, be yourself, You're sexy just the way you are.
I tell people there is no right or wrong direction for wardobe in their boudoir session. To an extent it really doesn't matter what your wearing, but rather the mood and feeling you want to invoke. This image for instance doesn't showcase particularly revealing outfit, or a sexy/sultry pose. Being yourself and being comfortable can be far more sexy than stripping down to show as much skin as possible. Relax, be sexy, be yourself.
