The shirt fits perfectly and like all Seidensticker shirts fit me well here the size that I have ever. FYI: Super Slim is the "Slimmste" what Seidensticker offers. Before that comes the normal "slim fit". The collar fits well, just what I miss are removable collar stays. Should, nevertheless, once bent (heat from the dryer) you can always discard a whole shirt. at least it is no longer usable as a business shirt. But we must not forget: It's a shirt for 39 or 29 euros currently. However, this category also have more restrictions and cares for me means that the shirt goes back again: it is extremely thin. If I'm wearing no shirt / undershirt underneath, you really see the complete skin at halfway favorable light. That is like saying at the price certainly somewhat understandable, and I have here also shirts by Seidensticker for 39 euros that are not so thin. For someone who is not so important and the occasional times requires a shirt but that's certainly still a very good choice!
