Sizing:
One size, ~40cm long (excluding the “polo” neck) and ~46cm wide across the shoulders and base of rib. It fits ~36inch shoulders/chest.
It’s fairly easy to change the size if you prefer a looser or more snug fit. When you get to the shoulder increases either work more increases (for wider shoulders) or fewer for a narrower fit.
