noticed a staggering lack of winter cosmetics for Italians, British and American. But I’ve done research to find real photo examples of winter uniforms used by US and British and Italians
Italians
The Italian M37 and M40 trench coat 
The Italians didn’t got many variations of uniforms but higher ranking members like marshals which would’ve worn a more bluer version
And ones with put trench coats would’ve worn an undershirt that’s a sweater 
A photo a group of Italians with all three winter outfits

Germany
The Germans had parka
These parkas was in any camo Germany made too but those where for “elite” units the average German would’ve had a trench coat or green parka
White winter over coat
They where pretty common but not so common

British the British had winter vest during the winter and also winter camo with trench coats emphasis on the British winter stuff
And a leather vest during the winter
