This must have been asked many times but I can't find the answer, so here goes.
Shirt sizing - how is it done?
What is meant by a 17/ 43 (for example) shirt?
Is 17 (in inches?) the circumference of the neck? What is 43?
When someone selling a shirt says it is 17/ 43 should I ask for more measurements, such as p2p, BOC length as I would for a jacket?
A link on SF explaining all of that would also be great.
As always, thanks for your time.
