Surprisingly (well, not really) complex...

So. There's still pondering taking place regarding the Alpirsbach trousers  legwear... because, well, my way of thinking.

The task is to make a reproduction of the trousers for an exhibition, which technically means that I could take the pattern published after the examination of the trousers garment, read the description, enlarge the pattern and then cut exactly that. But that, to me, would be sort of... cheating. I would much prefer to understand how the pattern was constructed originally, then re-do that construction process, and make the trousers with that re-done pattern.

Which, in turn, means that I have to understand the pattern. Not just which body measurement is found where in the thing, or where which part goes to sit on the body, or which bits to measure, or how much seam allowances to add to a given part, but also how to place the thing onto the fabric.

You see, in the original there's two main parts, and they look quite similar but they have different bits tacked on due to the fabric width not being enough to cut everything in one piece. My current hypothesis is that one leg was constructed first, cut out, flipped over, placed on the fabric and traced to make the second leg. For this, the (to me) logical choice would be to cut the right leg first, as this has only a small bit on the butt added in, and all the relevant long measurements are fully on the fabric.

It would look like this, laid out:

Some of the bits are very clear (there's a crotch middle spot, and the butt strip, and the foot part, and the thigh circumference), but the exact shape of the crotch cutout is a lot smaller and more pointed than a lot of the re-creation patterns of joined hose that I have found in other places.  So... is this correct? Will this work? How to reliably construct it?

Questions over questions. It does remain interesting, I can say!
