Ok, please nobody point out that this is the sort of thing they teach you in grade school when you're first learning to dress for the weather. I am aware of this. I had forgotten this, or perhaps simply did not really believe it applied to me the same way it applies to everyone else. Lots of warmth-related things don't apply to me the same as everyone else.
Heat escapes through the feet.
This is the first time in my adult life that this fact has been relevant. I got through entire Minnesota and New England winters without ever donning socks thicker than those I wear year-round. (My concession to the weather was my stomping boots, which are a good, thick leather.) On Monday, I was wearing over-the-knee regular sock-weight socks, instead of the lightweight trouser socks I normally wear (same weight as average tights), and I was comfortably warm. On Tuesday, I was wearing tights and no extra sock-layers, and I was not freezing, but cold enough to be very, very glad I keep a pashmina shawl at work. Today, I am wearing tights under warm, cashmere-blend knee-high socks. I had to take my fairly light-weight cotton sweater off when I got to my desk. I'm going to need to put it back on when other people start arriving, as a strappy camisole isn't terribly professional all by itself, but I am waiting until then. So yeah, socks. I need to start wearing socks. I don't have very many of those. So, if anyone is wondering what to get me for my birthday or Christmas, it appears I need more socks. I prefer knee- or over-the-knee length, as I need a layer of fabric between my skin and my braces.
If only I knew somewhere to get
awesome socks.
