Gentleman, if you start a trend of wearing long johns in public, your local menswear fetishist might actually die. Seriously, this cannot become a thing. If I see a fine man walking down the street in his thermals I'm wrecking my car.
If you ever encounter a short busty girl alone in the men's workwear section of a store running her hands over thick denim, manhandling flannel, or staring longingly at boots and gloves...it might be me being a little freak.
