This is the sweater I just finished for my sister Stacy.
I used ElizabethZimmerman’s generic in the round percentage system. Adding the cabling & ribbing actually gave me a lot of ease. That is Sadie wearing it for the photo, she is a girls size 12. Stacy is a junior size 1. Not too far off in size really. And, there is plenty of room left to stretch on Sadie. As of now, I am thinking it’s going to fit smashingly! I will try to get her to take a picture of it on. I won’t hold my breath though.
