I am going to make another pair in a lighter fabric this week for possibly more useful pictures, taken in the daylight.
As you can plainly see I am one ordinary sewer just trying to find a way to make some comfortable pants.
These three pictures here are of my P&S experiment, and I have to say I am pretty surprised and pleased with the results. This whole thing about starting from a pattern two sizes too small and adding on seems to have worked for me. As you can see it has given me the fabric where I need it (these are very comfortable pants) but has moved me away from the baggy back and baggy legs of earlier experiments. I think the legs are a whole lot more flattering and the wrinkles are surprisingly few, and essentially there were no post-first edition changes or additions to this pattern after I had done the initial on the fabric, cutting, and adjusting manipulating the pattern at the layout stage. This is actually pretty impressive I think and if a sewer got really comfortable with this method and her own body I can see getting to a stage where you could work with many out of the envelope patterns and get a pretty good fit by just pivoting and sliding as you cut. This pair is made out of a navy rayon blend and since I had run through this once with my test pair, I reckon it took me only about 15 minutes longer to do this pivot and cutting than if I had cut out this pattern unaltered.
I am definitely going to do a brown paper pattern edition of this pattern and try this approach again in another more fashionable pattern and have a good look at how to do this method on bodice fitting.
Since I graded the last method I should do that for pivot and slide.
Ease of use: first time I would say about a -B, once you get used to how to measure the pattern about an A.
Results without further fiddling about an A too, for a body like mine with straight sides, not really heavy legs but weight in the middle, the "menopad" my friends call it.
