Available in one size.

Interesting construction:
First knit the upper front section with the sleeves in one piece to the shoulders, then the left upper back section. Then knit the back semi circle in fantasy pattern, then the right upper back section.
Finally, at the front section, knit from cast on a semi circle.

Arrows show the knitting direction in a schematic.

The sweater will get longer while wearing it, due to the weight. Measurements were taken while the piece was laying flat and match the swatch of the fantasy pattern, before stitches are picked out. After picking out stitches, fantasy pattern becomes wider.
