(because it’s only technically spring, here.) First, determine the outside temperature. This system of layering will be too warm for above 20F, but below that should stand you in good stead.
Next, remember what your mother said: use the toilet. As an eyeglass wearer, I start by putting in my contacts so I don’t fog up every time I go in and out of warmth. I also apply moisturizer to my face, neck and lips. During the winter, I forego sunscreen to maximize what little vitamin D I can get from the sun.
In order, don:
1. Underwear (underpants, and bra if you wear one)
2. Undershirt (thermal or silk, longer length is best)
3. Longjohns (thermal or silk). Pull waistband over bottom of undershirt. This will keep your lower back (or overbutt, as my 7yo calls it) from unwanted exposure.
4. Socks, long and thick. Pull tops over bottoms of longjohns.
6. Pants, over bottom of shirt. Do NOT tuck overshirt into longjohns.
9. Boots, hat and scarf
10. Gloves/mittens. Gloves inside mittens is the warmest, but diminishes dexterity.
11. Coat. The lower the temp, the puffier and longer it should be, covering at least your butt and the top of your thighs.
This order of operations has you always pulling something over a previous layer, rather than tucking in a subsequent layer, which makes for a smoother line and means you don’t have to double back, for example if you accidentally put boots on before snow pants.

Stay warm. And remember, it’s only two more months until the frost date.
