Winter Clothing in 1st century AD legionary re-enactment

[Gaius Julius Caesar]

You don't need much common sense when you're getting serious death threats.

you'd be surprised....I'm still here!

Crispus, I believe Scotsmen wore trousers as often as kilts, even before they became British!

I would not advocate the wearing of Feminalia in the invasion period of Caesars Romp into Gaul,
although possibly, if they were stationed in the Alps, they may have adopted local custom prior to this too.
Or, perhaps, they just glared with envey at the locals they came into contact with during the winter, while they huddled near the brazier while on guard duty.
The disdain for the smelly barbarian custom could just have been a front back in civilised Rman cities....
Who knows for sure?
What we do know is, there is much said about painting of details on reliefs to fill in 'what must have been there'.
