This isn't a new one, exactly, but it keeps coming up, so maybe it'd be good to put the answer out where people can find it.
Yes, the fronts are asymmetrical.
I designed them that way on purpose, so that when the hood is buttoned and the fronts overlap, the buttons are still centred.
If for some reason you'd rather have the fronts symmetrical, place the markers as follows:
Work 5 moss, place marker, k43, place marker, and then work across as written until you get to the second-to-last marker. Then k4, k2tog, k38, place the last marker, and work 5 moss.
Alternatively, you can cast on an extra 12 stitches and then work as written otherwise, though you will have to adjust your stitch counts throughout.
