LX's pjs do not mention "handmade in Switzerland". I will have to check whether the bought one display the claim that the pj is handmade in Switzerland.
To answer to Sophia, the LX's pj' have a weave that is the same for men and women. I do not believe that it could/should be finer for men. And, the weave appears similar to the weave of my bought zim pj.
With respect to the tailoring, it never came to my mind to associate the words taylor and a man's pj.
