Suit Supply measures around the chest, so I did the same with my own jacket. I hung it with a clothes hanger and measured it with a tape around the pit area. Do I get the same measurement if I double pit-to-pit?
No, not really. But it confuses me when they say armhole and show something different. Okay, I have switched from body measurements to measuring my best fitting shirt. How do I measure the sleeve width and armhole? The details or the question mark says the same. Do I need to specify that, or do they figure it out?
