So, I've now gone out to a meeting fully dressed three times so far. While I've dressed fully at home for quite some time, and for extended periods of time, I found a few new sensations when driving en femme.
Sensations like seeing painted nails on the steering wheel. Driving with heels on the pedals. Having my peripheral vision limited a bit by my hair. No, neither of those last two were a safety issue, I just noticed how different/new it was.
But there was one more thing that I wondered about. The shoulder belt goes between a woman's boobs. When wearing forms in my bra, it gives a different view than normal since the boobs are a bit more defined. You might get a similar effect when wearing a cross-body bag. Obviously, I don't feel anything because of my forms, but I wonder if those with real breasts find this annoying. Or just a normal part of life.
