I have driven several times en femme for Halloween and loved it. It was about a ninety minute trip each way.
The top two things I enjoyed the most was being out of the house dressed and the fact that with each passing mile I that much farther away from anything from my male side.
I loved the feel of the skirt and then seeing my shaved legs in hose while driving. Seeing my nail polish on me false nails, the way the seatbelt went between my breast. Getting in and out of the car properly.
