Of course I do; I still dress up when the occasion warrants it. Also, I'm somewhat overweight, and more professional clothes are usually more flattering than very casual clothes. My normal work wardrobe is dress pants, chunky heels, an actual blouse, and some kind of jacket or cardigan because the building is chilly.
When I first started working full time it was in the back room of a university Library, and yet I wore suits, hose and heels; we all did, because we wanted to avoid looking dowdy. (It was the early 80's; and past the "decency" standards of my childhood, thank goodness. I clearly remember when my older sister had to start wearing a girdle to school every day in high school -- because not wearing one was unladylike; too much jiggle potential. ) I also still remember grilling my mother about why on earth she always wore only one glove when I was a child; she never really would answer that question, but over time I realized that she hating wearing them, and she cheated by only wearing one and carrying the other with her handbag when she left the house. I, OTOH, love gloves, especially nice kid gloves, and having to keep track of the unworn glove seemed like a PITA to me. (Mom's fake-out meant that she could not put the second glove IN her handbag, of course, because the fiction was that she had only taken it off momentarily, and actually putting it away would have made the ruse obvious.)
DH normally wears a suit every day in case he has to take a court appearance (not right now, as the courts are closed.) I still wear suits to business conferences. I own jeans, but I don't wear them to work. (I will wear them outside of the house though, which I will not do with so-called "active" clothing unless I am literally exercising at the time. The one public place that I will wear that sort of thing is ironically Disney World, because of all the walking in the heat.) My workplace accepts very casual clothing (though not shorts), but I prefer a more professional wardrobe for myself; it makes me feel more confident.
The one "normal" piece of modern clothing I absolutely will not wear in public is sneakers -- I hate sneakers, and only wear them to places that require them to protect the floors. (FWIW, I was 11 when I got my first pair of sneakers, which were strictly for wearing during school gym. ) At WDW I wear sports sandals or hiking shoes, because they can take getting wet and not chafe my feet.
