I'm doing a private party for a friend of mine and I'm dressing full en femme.
I thought about dressing up as a female police officer as there are some coming to the party (my friend is in the police force).
The best thing about it is that I'm doing the Djing as well, so this will distract any notion that I'm a CDer.
I like the thread that foxyjj111 said about the female attention.
I've dressed up en femme during halloween loads of times and the reaction you get from females is fantastic.
But this maybe due to the fact that I'm djing at the time and I'm the centre of attention, but all in all it's great fun.
Just go with the flow and enjoy yourself
