Version 2 (the one I finished)
CO 68 sts. Inc 1 to 84 sts (k4, m1, k4, m1, k4, m1, k5, m1). Set short rows from centre front: 8, 12, 17, 23, 32. Work 4 rows of short rows. K1 row, then inc 2 to 120 sts (k2, m1, k2, m1, k3, m1). K1 more row, then continue remaining 6 short rows. K1 row. Inc 3 to 168 sts (k2, m1, k3, m1). K4 rows. Work extended chart (with extra diamond; in R17, inc to 196 in pattern (k6, m1). I had 14 pattern repeats. Finish chart. Work 16 more rows before dividing sleeves: back=61, f=57, s=39 ua=10.
Sleeves: knit 40 rows and then a decrease row; then 4 sets of knit 9 rows and 1 decrease row; then knit 5 rows and 1 decrease row, followed by 4 more rows, then ribbing.
I left the upper sleeves loose and decreased lower sleeves to 27/28 sts but 34 would have been better (they’re a bit tight). Sleeves used 61g of yarn (each).
For the body, I knit 24 rows and then decreased 4 sts around (21sts from CB and 27 from CF), fitting the front increases into the sides and the back increases into the middle. I then knit 13 rows, 1 decrease row, 13 rows, 1 decrease row, 10 rows. Then I did 4 short rows in the back: 4 from side, then 14 from side. I knit 13 rows of k2p2 ribbing before doing a kitchener bind off.

Version 1
Cast on # in size XS for a slightly smaller neck.
After increase round 2, add short rows to back neck (markers from CF: 12, 18, 26, 36, 50). K 3 rows. Start chart. Inc 3 in R17. Tryon: conclusion, neck is too large.
