Here in Michigan, which gets pretty much everything but locusts, it's normal to have several layers made of differing materials/thicknesses.

Sunday was rainy and 38 degree. Friday will be sunny and 80.
When we shop for a new house, we look at closet space first.

Generally, with varying thicknesses, I just do a baselayer, jersey, and jacket. Too may layers, and you start losing daylight just getting dressed.

- thin baselayer - thick baselayer
- thin LS jersey - thick LS jersey - normal SS jersey
- light jacket - heavy jacket - rain jacket
And then you buy a million of each so that your laundry pile can get as big as your pool table before you have to actually wash them.
