Before I show you what muslin 3 looks like I first want to show how I adapted muslin 2 into muslin 2.1 to determine how to change the pattern.
I started with a very simple alteration. Muslin 2 showed a lot of fabric being pulled into the crotch indicating the crotch length was not long enough. The trousers were also very tight across my thighs indicating I needed some more room there. I solved both issues by doing what “The Perfect Fit” one of the fitting books I own, calls a full thigh adjustment. The pattern is extended both at the side- and inseam which lengthens the crotch seam and increases thigh circumference. The red lines in the schematic below indicate how I re-sewed the seams in muslin 2 and changed the pattern for muslin 3. I also removed the gaping I had at the yoke.
These 2 changes already made a huge difference to the fit as you can see below.
After I changed this I noticed I could remove some of the wrinkles I still had at the front by pinning out 2 darts. I made this alteration in the pattern by slicing the pattern open and overlapping the edges to simulate the dart I had pinned out. This does not change the side seam.
At the back I thought I probably still needed to add some more length to the crotch seam so I sliced the muslin open horizontally and inserted some fabric. This did seem to improve the fit at the back and the muslin became more comfortable to wear so I made this alteration in the pattern as well. This is done by slicing the pattern open and creating a hinge point at the side seam. You can then add a wedge to the pattern by sliding the center back upwards. The side seam does not change.
After I had made all these changes I decided it was time to make muslin 3 to check whether the changes I made on the pattern were correct. Unfortunately I ran out of muslin fabric (why did I ever think 3 meters would be enough???) and had to use something a bit lighter weight than ideal but I didn’t want to wait until I had the opportunity to get some new fabric. The fit is still not perfect but I think you’ll agree this is definitely an improvement over where I started with muslin 2!
How many muslins do you think I’ll end up making before I dare cut into my denim?
