I wear tights that are like hosery under dresses and skirts, but I don't wear leggings which some people call 'tights'. I'll wear them for athletic stuff, but not for work. My legs are NEVER cold though, so I only wear tights as a fashion accessory (which is why I had to buy some as I never bothered when I was an engineer).

Yeah, what is 'work appropriate' for my company is very individual. As an engineer, I could wear whatever I wanted (and hardly ever heels due to needing to wear an ESD strap on my shoes on the test floor) and most engineers dress like slobs. I refused to do so so I was always just kind of cute casual. If I wore jeans, it was usually only on a Friday and always nice jeans with a jacket or something slightly dressier so that I didn't look sloppy.

Now that I'm in HR/staffing, I'm not only seeing tons of other employees every day, but I see outside customers too. I should be wearing more typical business casual attire (most of my group does). I still keep my same jeans rule, but interestingly enough, most people in this department dress like slobs when they put on their jeans on Fridays. It's really weird to me. They dress nicer during the week, but much worse on Fridays.

The other piece of the puzzle is that I travel and represent the company a lot. When I do, I am expected to dress casual because we are a casual company. BUT, I need to wear company branded stuff as much as possible. I hate, hate, hate what I look like in a polo and khakis which is what most of the guys in my situation wear. I need to get more creative. I want to appear like a hip but mature woman. Finding that sweet spot between 'mom' and 'cool' without crossing into 'trying too hard to look young' is tough! Toss in the company branded items (which are almost never 'cool') and you get a real challenge!
