This is a pattern for a coat/robe( I’ve used it for both). Its made with a super bulky CYC #6 blanket yarn. I used Lion Brand Cover Story because it doesn’t shed like bernat.
Gauge isn’t really important in this pattern because you are working from a measurement. It includes instructions to make several different sizes from child to adult small to 3xl.
It can be made in any length you prefer. The one pictured was made to mid calf.
