The slip is made of synthetic fiber with elastane share. In the angle he is again reinforced by a location. He has a slight rubber coating on the leg edges that can not be felt. Although I prefer to wear black briefs or thongs simple, so I like this Lace AUC. He wears great.
For size: I order at Slips like a size larger so that it becomes clear nothing and tweaks. The size 42 is tight, I have with any other brand of size 40 and the here of Esprit seems to me less. Rather scarce size 42. Esprit has always scarcely measured quantities, as far as I have experienced it, even in clothing.
