So the first item to share is the Style Arc Barb trouser in navy ponte.
I had the size 16 pattern, I measured between the 16 and 18 on my measurements. I have chunky legs for which they don't include a measurement, so I decided to add 1/2" all the way down both sides and at the top, but not at the hem. This makes the crotch longer as well as the legs and body wider.
When I sewed these up I waited until I could get some 2" elastic and worked on other pieces in the collection.
I used the measurement length for the size 16 elastic (37" but 3/4" for the seam), but in wear this is slightly too loose.
The pants are comfortable but fall down a bit at the waist, tightening the elastic would probably resolve that.
Sadly these look worse at the back than my track suit trousers I wear when I am being comfortable around the house. However that might be due to fabric rather than cut.
Note to self for next time. I tightened the waist elastic slightly and scooped the back crotch. They do fit better than the photos above after that and have been worn a lot, but sadly the fabric is pilling. However they are very comfortable and have been worn a lot. I suspect even more improvements would be seen from a full front thigh and full back calf alteration as they do pull slightly in these places.
