I am 6'0" and they recommended a 40 long, in retrospect it should have been a 40 regular. I'm not sure how much longer the long is over the regular, but less length would be preferable. Having said that I have seen a period photo where the tunic does appear to be quite long. I should mention WPG did offer to exchange it for a regular, but the cost for me to ship it back to them would make this too expensive an option. I also washed it so didn't feel it was fair to return it. I will see how it works and if it really looks odd, I'll either get it altered, or buy a 40 regular.
