I went back to see if you're married. There is be a big difference in the approach for a reveal if you're already married or have a girl friend. Kids? No kids? I did see you asked this question more than two years ago. No luck so far? If you're going to tell a woman with whom you have a relationship I recommend telling her exactly who you are as it relates to wearing women's clothing. Usually fetish is associated with a singular style or garment; panty fetish, hosiery fetish, etc. I've never heard fetish applied to the entire ball of wax.
Even trying out the idea for a costume party or Halloween (Slovenia?) runs a risk. The women I know would see the progression from a fetish to full on cross dressing was nothing more than a ploy. Be truthful in life.
