There is nothing more lovely than a simple north facing window for creating a flattering light for the female form, of for female faces.

Lighting Diagram

With a north facing window above and to the left of our model Holly / IvoryFlame

You can soften the light down on a sun facing window with net curtains, but any window facing away from the sun will give you this wonderful diffused light.

Of course light levels may be very low, so you should increase your ISO rating so you can still comfortably hand-hold your camera without camera shake and your model can hold their pose without movement.

Just look at the way that lovely softlight gives wonderful direction in the shadows, but very soft transitions, revealing the form perfectly without harshness.
