Try a classic soft focus shot.
Stretch some clingfilm over your lens or filter to prevent damage, then smear a thin layer of Vaseline around the edge of the clingfilm leaving a small clear area in the middle (do not smear Vaseline directly on to the lens).
Now try photographing a close-up of a female or child.
You should end up with a wonderful soft focus image (very flattering!).
Your aperture will determine the amount of soft focus.
For a slightly different effect, you could also try stretching a pair of tights (or part of the material) over your lens and experiment with different aperture sizes to get various levels of softness.
