This pattern is really an overadaptable tutorial for you to knit your exact size.
The “available sizes” are really given so you have an idea of the needed meterage/yardage.

Purple Rain is a comfortable oversized cardigan that knits up really fast.
It’s knitted top-down with contiguous set-in-sleeves.

You need to know how to knit, purl, increase and pick-up stitches.

Have fun :smiley:
