I have a big problem with:
1. Judging people by what they are wearing; as long as it's clean, in good repair, and fits well, it shouldn't matter. The shallowness inherent in the concept of "professional dress" repels me. It kind of reminds me, in a milder way, of deforming the feet of upper class Chinese baby girls; a status symbol that sorts and limits us.
2. Having worn "professional dress" when necessary, I know that it restricts my physical movement and activity. No, thanks.
3. Taking things to the dry cleaners; I expect my clothes to wash and wear. As a busy professional, I don't have time for anything else, and dry cleaning, while improving, is not environmentally friendly. AND, since I tend to spill, food, drink, and ink, they can't be too expensive to replace when stains don't come out.
To be honest, when I see a suit, my gut automatically tells me, "Snake. Don't trust him or her." Maybe that's just my working class roots reacting. I freely admit to bias.
I dress for comfort in the environment I'm working in. I can do so without being sloppy. Thankfully, in this region, that's good enough. Being comfortable allows me to focus on my job, instead of on what people with limited capacity to see others think. And there certainly IS an element of PR in my profession; I've discovered that once people have worked with you, they tend to see you as a professional, instead of seeing what you are wearing.
Because that's what a professional is; someone who practices a profession. "Professional" is the person, not the clothes.
