Not sure I should publish the pattern, cause it's not really refined and well planned from the armpits up, if I had any motivation left I'd probably do it once more and decrease more stitches on the raglan part but I just can't be arsed and to me this is good enough as it is.
So I'll just publish a rough pattern to give an idea how this was made and it's up to you to make desired changes should you wish to try this at home.

Instructions:
Back:
Cast on 58st. Knit garter stitch for the first 4 rows. Knit stockinette for the rest of the piece. Decrease 1 on both sides every 14 rows from the hem up 4 times. When you reach 60 cm cast off 3st on both sides and start raglan decrease decreasing 1st on every 4th row at both ends of the row 6 times. For the neck decrease 10 st at the second last row in the middle. Leave the stitches on both shoulders on hold.
Right front:

Cast on 30st. Knit garter stitch for the first 4 rows. In order to make the cable pattern fit nicely on the arm, place the pattern bit off from the center of the sleeve towards the body. On the right sleeve knit 12, begin the cable pattern for the sleeve and knit the remaining 10st. On the left sleeve do the opposite. Add 1st on both ends of the row every 8th row 6 times. After 40cm start raglan decrease same way as on other pieces. Leave the remaining stitches on hold.
Sow the pieces together. Pick up stitches from the sides of the front pieces and knit garter stitch for 5 rows and cast off loosely. For the neck pick up stitches from all the pieces left on hold and knit one row. On second row decrease stitches by half by knitting every 2 stitches together. Knit the next row. On the third row knit every 2 stitches together on the other sides but knitting stockinette on the back side. Knit garter stitch for about 5 rows and cast off loosely. Add the hooks and you're done!
