Gauge
14 sts and 20 rounds to 10cm / 4in over stockinette worked in the round, with yarn held double, using gauge-size needle

Sizing
Finished bust circumference: 93 (101.5, 110.5, 122, 133.5, 142, 151, 162.5) cm / 36½ (40, 43½, 48, 52½, 56, 59½, 64) in.

This sweater is intended to be wide, cropped, and to hang slightly bell-like from the shoulders. To fit as shown, it should be knitted with at least 10cm / 4in positive ease at the bust. Pick the size at least 10cm /4in above your actual bust measurement, and if in doubt, select the next size up. Length can easily be added to the sweater to make it less cropped. Shown in the first size with 12.5cm / 5in positive ease.

Pattern notes
The sweater is knitted from the bottom up, and begins with an inch of rib, after which it is worked straight to the underarms (length can be added here to make the sweater less cropped, if required). Two sleeves are worked, then body and sleeves are joined together to be worked in the round. The yoke is shaped by decreasing stitches at an even rate from the body only, and, when the correct depth is reached, the stitch count is reduced further for the neck. A deep ribbed roll neck is then worked to complete the sweater.
