I used to manage a retail clothing store where dress code was paramount. We had an 'image' to uphold. It was a pain.

Anyway, I used to allow my employees to have bare legs in the summer under two conditions....1) their skirts were to the tops of their knees (no minis) and 2) their legs were in good condition. If they had a thousand mosquito bites - wear hose. If they took a spill on their bike and had road rash - wear pants. No bare leg 'ickyness' was allowed. Everyone seemed happy with it. Oh, and this ONLY applied between Memorial Day and Labor Day (we were in the north). The rest of the year, hosiery was a requirement.

I think that for your office it partly depends on your location. If you live somewhere warm and casual (like FL) then no one will care if everyone has bare legs. If your office is down the street from the fincial district in some major city, pantyhose might be a good idea. Perosnally, I think it's pretty relative and it's hard for us to judge as 'outsiders', you know?

Luckily, I'm now an engineer and having any 'style' at all is clearly optional for my profession so I never have to worry about it again.
