That's not the original model.
It's the replacement they produced in order to cut costs, after the sale of the company to an LLC and a factory move to an outlet in Poland. And there are two differences between the shirt they are now offering and the original.
The original model (#207-0805) was the model used in all X-Men films as well as The Wolverine. Supplied by Zimmerli as a Swiss company. When they were bought out in 2013, the factory moved to Poland, and cost cutting measures were begun. One of those measures (Info here gleaned directly from the key retailer of the original shirt from the original Swiss operation) was to changed to the original model by cutting the waist fall, and adding a band.
Whereas the original had the open hem waist with the curtained stitch.
This subtle detail made the shirt do something rather annoying, in that it ( the new model #207-1419) now bunches/rides up around the high waist and constantly needs to be adjusted down beneath the trousers.
The shoulder bands are also closer together into the taper on the original model.
The original shirt is tiny when not worn. It stretches broadly to fit the wearer and, once taken off again, reverts back to its original shrunken below size form. The replacement can be starched out over a shorter amount of time due to the lesser material quality overall. These two points make the replacement shirt substantially less in cost. As was the original intent when it was altered.
This is sort of inside researched information and is, of course, up for conjecture and debate. It's just the information I have. But the point it, yes, there actually is a different shirt on the Zimmerli site as opposed to what they once offered. There's a cached page you can also find fairly easily that shows it discontinued and a link to the suggested alternative.That said, in the end, it doesn't matter to me personally. I've gone to great lengths to get everything as close to authentic as possible. I don't want the shirt that is the replacement for the original. Call me anal. I want the original.
So there in lies the distinction.
It's just a personal preference. Just like my decision to now attempt to also have the grommeted belt recreated to screen, in addition to ordering a stand-by which will suffice if it ( the attempted grommet build) doesn't work out.
It's all a matter of preference
