extra set of sleeve increases on the ws at the shoulder head to have bit of extra room (+2st on the sleeve)
Trying it on to work out waist decr/hip incr
Ribs: incr 11 st along the row to be more comfortable (total multiple of 4)
K1 for selvage, k2 p2… k2, k1 for selvage

Collar: multiple of 4
K1 for selvage, k2 p2… k2, k1 for selvage

Sleeves:
On 4dpn to avoid overstretching with magic loop
Started the ribs 6-7 rows later. No thumb hole.

Button bands:
Trial and error to have a neat finish
Pick up a multiple of 4+2 making sure to start right at the top of the collar (in the bind off chain) and finish right at the bottom (in the bind off chain of the ribs)
then pick up a selvage stitch on the back strand of that bind off chain, one at the top of the collar and one at the hem (use the tail) +2st, total multiple of 4. The selvage st will roll towards the back and make the edge very neat.
SLIP THE FIRST ST OF EACH ROW for the buttonband.
From the right side: Slip 1 for selvage, k2 p2.. k2, k1 for selvage
From the wrong side: slip 1 for selvage, p2k2.. p2, p1 for selvage.
Check placing for buttonholes.

I like to bind off in pattern from the wrong side
I’ve used the recommended needle sizes for the project but I had to go up 2sizes for the bind offs (they were too tight otherwise)
Ribs for hem and sleeves:5mm BO 6mm
Collar and buttonbands: 4.5mm BO 5.5mm
