Hi drumacat,
You’ll need to let us know a few things…

  1. What is it you’re knitting?
  2. Do you have a pattern?
  3. What is your gauge with the size 10 needles & worsted weight?

i was gonna knit her a skirt.
no pattern though just gonna wing it.
gauge is
17 st= 4’’ on size 8 needles

If she lives near you, maybe you can sneak into her closet with a tape measure and measure some of her skirts or pants…
