Long and wide

Had I ordered this shirt because I'm tired of having a bare back. I have a long back and normal T-shirts are often a bit short. The photo shows indeed a rather long T-shirt. But what I got is also very far. On the Einnäher is XXL but it is more an ordinary 3 or 4XL, ie more than a sack of a sausage. Material and workmanship on the other hand are good and high quality. Can not quite understand why the cut is rated so different in the reviews. Apparently varies the fit.
