I found an old render from 2020, and I liked the shirt. I dredged through my oldest .blend files and finally found it.
Also, I fixed up the shorts some. There is still more work to do, but at least now the belt loops and pockets look closer to correct. Yes, she's still a stylised character, but I like the look better now. I had to write my own custom smooth modifier to make the shorts/shirt look correct after posing.
