You could try to draw something like this with fabric pens/colour onto a white jacket? Some of the shapes are not regular, or even slimmer. And the blocks of colour don't look solid. I bet that you could ape this with pens quite well.
Sorry I don't know what it takes to fix painted on colour. (Is fix the right word? I mean make permanent)

You could even draw it so the lines of the pattern at the sleeve heads continue over the seam onto the body (drawing onto the finished jacket). I think that would long great.
And you can add the red bits if you wanted. Is that text?
