Layered Clothes.

Layered clothing is a thing in the late Middle Ages. There's been layers before, obviously, and there are passages in the Nibelungenlied that point towards some of the additional layer garments (like a cloak) being not strictly optional bad-weather garments for someone like a queen, or very high-ranking woman. 

But this is the first image that I have seen which very clearly shows two doublet-type garments worn on top of each other: 

This is a detail from a "Carrying the Cross" scene in the Bode Museum, Berlin, dated to c 1425. You can find the full piece and the corresponding database information here in the Berlin Museums Database.

The man on the far right is clearly wearing long hose or joined hose, and he is also wearing a doublet-like garment with button closure in the front that goes down to very shortly above his knees. Interestingly, the front is unbuttoned up to his belt, and the corners of the garment tucked into the belt. This reveals a shorter doublet-like garment, laced close. The guy to his proper right is wearing comparatively boring ringmail and a breastplate, and something under the ringmail which might have a sleeve that forms soft vertical folds, or the vertical lines might indicate some kind of padding and quilting (the garment from Chartres also has vertical quilting lines down the sleeves).

This is certainly... interesting. Very interesting. If these garment types were layered here, is that a common occurrence? Would something like the Chartres garment have been worn over a second doublet-style garment, then a ringmail? There are rust spots on the lining of the Chartres doublet which point to something metallic having been in contact with it. 

Only a shirt underneath the ringmail is theoretically possible, but might not be the most comfortable arrangement. We do have some few examples of laced-closed doublets that were definitely worn under armour (see for instance this article, and sorry for the paywall). So - how many of the pieces we see on late medieval paintings were worn solo? How many were worn over a second layer of armour, be it textile, metal, or both? 

It also adds some more interesting aspects to the Oswald reconstruction. Though due to time and budget restraints, I don't see a full ensemble of two doublets and the ringmail come about... 

If you should have seen anything similar somewhere, please do let me know! I am still all excited about this discovery and would love to know if there's more...
