Sometimes professional business people wear the darnest outfits.
One time a lady showed up at my doorstep, she said she was a realtor handling property adjacent to mine. She wanted someone to walk the property lines with her. Her blouse neckline plunged down to nearly her belly button, and her skirt had a slit on the side that went up to her thighs, and she was wearing knee-high laced boots with 6-inch heels [we used to call 'fuck me go-go boots']. I loaned her a pair of my waders, and I spent the next 2 hours walking through swamp and forest with her.
I own a commercial building in town that I needed to have the fire sprinkler system inspected. I contacted a company to do that job and they sent me an office worker who again was a hot girl wearing make-up, a short skirt, and stiletto heels. I asked her if she was really dressed for crawling around in my basement. She insisted she was, so off we went. Her boot heel got stuck on a stairwell, and she was covered in cobwebs when we were done.
Proper attire for an office is not the best thing to wear out in the field.
