I was one of the last hold out as far as wearing hose. I noticed that in AZ, everyone wore hose, no matter how hot it was. When I moved back here, as soon as one warmish day came, the hose came off. Now people go bare-legged when it's 45-50.
I can't do that, so I pretty much go from tights, which I do wear with dresses and skirts to bare legs. But, there is a time, mostly in the spring and a bit in the fall, that hose meet my warmth requirements. It's only a few weeks. Mostly, I try and wear the tights.
Since I am not working now, I haven't worn skirts to class since the end of the winter, unless it was a warm enough day to go bare-legged. Wearing hose at a university would get me laughed outta there.
I also wear hose at more formal things in the evening, in the winter. For example, a wedding where I am really dressed up= no tights, but hose.
