The dude sweater https://www.lovecrafts.com/en-us/p/the-dude-knitting-pattern-by-andrea-rangel

Help. I think this is going to be way too big. It says to cast on 111 stitches, but this is bulky wool. For my size I would think it would be 70 stitches. Any advice?

The sweater is knit in 1x1 rib throughout. The gauge is 21sts and 21 rows to 4 inches in 1x1 rib so at that gauge, 111sts is 21 inches for the back or a chest measurement of 42 inches.
