Changing the pants from zip front to elastic was the easiest bit. Changing the bum and leg on the pattern was much more challenging. Before I started cutting into the muslin, I searched through the web for tutorials on how to alter the pants pattern for different lumps and bumps for my body. The surprising thing was that, the most useful sites for my body shape were the ones that weren't in English - one in Spanish and one in Russian. I'm not a Spanish nor a Russian speaker! Thank goodness for Google Translate. I was able to figure out what to do.
The pattern comes in Slim, Average and Curvy versions. I cut a size 14 Slim first. I figured that I would try the Slim version first and if that failed, then I would try the Average version.
As I was testing out the muslin, I also discovered more important info about my body shape for future alteration purposes. I apparently have normal size front thighs but thinner back thighs. I have to drastically reduce the back thigh width of the back pattern. I did that by making a big pleat from the bottom of the bum all the way down to the hem of the pants. That is exactly why pants (RTW and previous self-made ones) often have too much bagginess under the bum.
And my back crotch curve is almost a 90 degree angle. Who knew?
Also, I realized that I will have more than 1 pants pattern for non-stretch woven material. The Office trousers will have more ease than the cotton chinos. So I'll have to make another muslin from this pattern for much more fitted pants like chinos.
So here is the final product from different angles:
These are the least baggy non-stretch woven trousers that I have ever owned (RTW or self-made). Of course my stretch woven skinny jeans/knit pants are much more fitted but I have too much non-stretch wool blend fabrics in my stash that I need to use.
Now that I have figured out the bum and upper thigh situation with these tapered pants, I can just change the pant leg width from the knee down to make straight leg pants and boot cut pants. May be one day I'll change the elastic waistband back to a zip front waistband!
