I am the opposite, though not truly about circulation. That I am unsure of. What I meant was, I am odd in that as long as my bottom half is warm, I am warm. I am known for NEVER wearing a jacket, typically a T-shirt, sweatshirt, then blue cotton button up shirt and that is it. No jacket, BUT I have to have my leggings under my jeans to keep my legs warm. Take them off me and I am SUPER cold.
Edited to add that where I live, like right now, it is -7 degrees below zero Fahrenheit. That is -23 Celsius. It was -14 (f) earlier this week.
There is one caveat here though, while I think the calorie rating of my button up work shirt is only 2-3, they tend to be thick because it prevents arc flash of high voltage circuits. Because of that they are warmer than most blue collar workwear.
