This is a fully true story that happened about 10 or 12 years ago, when I was a regular wearer of pantyhose.
I'm a guy who likes to wear pantyhose. But I'm not what you would consider a cross dresser. I don't dress up in women's clothing, other than the pantyhose. While I like some of the practical benefits they provide, such as extra leg support, I have to admit, I genuinely like the fit and feel of them under my pants. The feel as they glide against the material of my pants is a great feeling to me. As I said, normally, I don't wear other items of women's clothing, but one day I passed a store that caught my eye and gave me a naughty inspiration for showing off a bit--which I also like to do.
I don't recall the name of the store. It was in the back part of a little outdoor shopping mall, and apparently specialized in dresses and outfits that a stripper might wear onstage. I couldn't resist the urge to stop in and look around. There was a youngish women working the shop who was very friendly as I walked in. She asked if she could help me and I told her I was looking for a costume I could wear next Halloween, as I wanted to dress up as a stripper (fast thinking on my part). So, I started looking through the racks to see what was available. BTW, I was dressed in a polo shirt, shorts and suntan pantyhose that day. I'm guessing she was sharp-eyed enough to notice the nylon luster from the sunlight through the windows on my legs.
I pulled out some slinky dresses as I went along and asked if I might be able to try these on.
She said, "Sure, no problem. The dressing room is right here."
She motioned toward a little room right beside the front counter with a curtain pulled across the opening. I could tell instantly that this was going to be my lucky day for a little exhibitionism, as it was obvious that the curtain wasn't well made and would be difficult to make it completely block the view from inside--as if I would want to. I took the 5 or 6 dresses and skirts into the room with me and pulled the curtain sloppily across the opening, leaving a gap of 2 or 3 inches, turned my back and immediately began taking off all my clothes, except the pantyhose. She was nearby outside, doing busy work since there was no one else in the shop. If she had wanted to watch, she would certainly have the opportunity, and maybe she was.
After I changed into the first slinky, semi-sheer dress I opened the curtain and asked how she thought it looked.
She thought it would look great on me and asked me what I as going to do for shoes (I was standing there barefoot in my pantyhose right then). I asked if she had some high-heeled shoes I might be able to wear and she went to get me a pair that would fit.
By this time I had re-entered the changing room and started to change into another outfit, so when she returned with the shoes I pulled back the curtain a little ways as I stood there wearing only my pantyhose. From outside, she would have had a pretty good full length view of my side/hips but not the full frontal. Now that she had entered the changing stall and I turned toward her to take the shoes, she could clearly see everything through the sheer pantyhose (no underwear beneath). I took the shoes and slipped my foot into one.
