In short, no.
I started down this path many years ago in an attempt to minimize hearing crap on a CB (I drive a Semi) about being a slow old person in an old truck and I should retire. My first foray into this was a cheap wig. I soon realized that that made me look like an old hippie with bad hair. So I upgraded the wig over time to a professional quality one. Along the way it also became very apparent that getting out of the truck to fuel and do truck business meant that I had to pass as a true female. This resulted in Breast forms and eventually Hip and Butt pads.
I have had to add a an number of clothing articles over the years and the ability to accessorize and mix/match different articles became important because of limited storage space in the sleeper. I have even ventured into the world of Pheromones to complete the ‘sale’ of the image.
Over the many years I have perfected my look and image sufficiently to fully pass in most all places. I have perfected the explanations for the voice, hands and the part of the arms I will show (expose). I have not been questioned on this in years.
But that leads to the question: is it just the clothes?
I my case I feel the answer is no. Clothes are like an accessory to the Body and the Image you present. Between shaving the body hair, adding forms and wigs to perfect the “base” look, then adding makeup and Pheromones, the clothing finishes off the sale of a Genetic Female look to those around you.
if everything is right, you pass. if not, the ‘tell’ gives you away, and the clothes don’t help the “sale”.
