Here's an idea the works for me....and thank heaven for digital cameras!
First...dress the way that makes YOU feel the most girly....now....gather up a few copies of Glamour and/or Playboy....and find the models with your favorite poses. Light some scented candles...some nice music....a slow speed fan....mmmm
Now...with your camera at the ready....try duplicating some of the poses...including as best you can...the facial expressions.
Most of the photos will be downright silly....but believe me....feminine you will feel....and besides, you can immediately delete the pics you don't like. But you're going to find some you do like...these you copy to your PC...and then photoshop to your heart's content.
See if this works for you. Let us all know!
