My intention is to make size 3 but make the sleeves wider.
Stitch counts:
114; b=37, f=33, s=22
171; b=56, f=49, s=33
228; b=74; f=66, s=44
285; b=92, f=82, s=56
342; b=111, f=97, s=66
358; b=115; f=103, s=70

To make the neck smaller, I used tubular cast on to CO 86sts with 3.25mm needles. 7 rows worked.
Switch to 4mm needles.
I worked 1 row, then increased to 114sts (using YO increases; k3, m1x14, k1, repeat
BOR is middle of left sleeve.
Work short rows before starting colourwork. Start short rows at 59sts. k 1 row. Move short row 3 to front on each side. Move short row 3 sts to front on each side. k 1 row.

I modified the colourwork chart to randomize it – if you want a copy of it as a pdf or excel file, let me know. I also worked short rows in the chart on rows 3, 6, and 11.

front=103, back=115, s=70, ua=7

Sleeves: 77 or 76 sts for sleeves. 32 rows worked. Decreases: dec either side of centre two stitches (k1, k2tog, work to last 3 sts, ssk, k1), work 3 rows; repeat 14 times. Cuff: decrease to 36sts and work 17 rows p1k1 ribbing. Sleeves used 50g of yarn.

The body was knit straight until the band where I decreased 22 sts around to bring it in slightly and keep it from flaring. 17 rows of ribbing. Body length from underarms is 12”.

Yoke depth is 10-11.5”.
