Quick pics out the bag. Big thanks to @guiltyparty for the rapid fast shipping speed and IH like online communication.
I was really perplexed at the measurements vs the discussions about sizing people have had on here. I think I figured out what’s going on. This shirt has smaller arm holes than any IH shirt I’ve owned, and it’s giving the perception that the shoulders are snug.
You can see by my photo the shoulder seams drape over my shoulder just a bit but it does feel slightly snug in the shoulders, and it’s due to the high armpit cut of this shirt. While all other measurements in a large would have worked, the shirt would have been too snug in the large size. This shirt fits me great, I must be square shaped. Anyhow hopefully this helps someone else with their sizing choice from a retailer with this in stock. I would stick with your normal shirt size if you are between sizes.
