The undertunic laid out so you get a better idea of the general form of it. Almost no fabric went to waste when cutting it, I should probably draw you a graph on how I cut the shirt... let's just say that when I realized how it works I had that feeling you get in tetris when you finally get that long red piece.
This is the part that makes moving your arms around really easy, the extra rectangle that goes under the arm. It also allows the rest of the shirt to sit tightly across the chest meaning you'll need less fabric while sacrificing nothing movement-wise.
Side view.
Seams, front and back. There's in total three stitch lines each seam: first of all, making a single line of stitches results in a seam that tears easily and the gap between fabrics allows warmth to leak out and cold air to sneak in. In many Medieval garments seams are
felled one way or another. It's a lot more work but imo worth it.
The collar. Again warmth and coverage are important functions, I wanted a collar that closes very close to the throat both so it doesn't let cold air in and to cover up well (Y90 clothes seem to be designed to expose as little skin as possible). It doesn't show well in the photo but the collar is tied on both sides with strings and is cut open on the right hand side.

Not much done embroidery-wise but all of it technically unnecessary.
