From the Designer:

This is a great coat for cold weather - consider going up a size if you want it to be roomy enough to wear over another sweater for extra warmth. The stitch pattern is easily memorized, and the sweater works up very quickly. Instructions are given for both a men’s and a women’s version. Customize it to your liking by working it to match the length of a favorite sweater or coat. -Sue McCain

Sizes range from XXXS (28.5”) to 7X (76”).
