Size gradation deviated

The shirt is well made, but the customer is of little use because it is delivered in excellent wrong sizes. I own several similar sport shirts (approximately 3 several other brands) and all brands fit me size L (even loosely).
As other customers have warned of the size problem, I ordered a precaution a XL shirt.
So it was also on the label, but felt it was like size S - so we went back. This action has a lot of people employed unnecessarily and deserves no one has something in mind. This should not happen in the shipping trade.
