You and your neighbor must be very close. Is the hole for the neighbor? Or..is the hole for a man who wears ladies' knickers?
a sheepie (a fleece, actually a synthetic one, cut and sewen into a kind of vest shape), under a heavy coat with a hood, and two layers of undershirts under my regular shirt. and when it gets really cold, there's a kind of leather vest (the first one i made for myself was when i was in the society for creative inacrhonism., the one i have now is my second. they last decades and its a good thing they do), i wear over the sheepie under the coat. i used to have a parka for below freezing weather. they're expensive these days. i guess they always were. anyway i wore out the last of those i had almost ten years ago. the layers i have now when i need them, are sufficient and not too cumbersome, when i don't have to spend a lot of time out in it, which is a thing i'm very thankful for that i'm lucky enough currently to not have to.
As its 'Black Friday' here - these are apparently on offer in some stores: HuffPost is now part of Verizon Media
