Now I read here that the trouser waistband is quite comfortable and I therefore Gr. 20 ordered. To my great joy - it fits like a glove. Only the leg length is too rich, but I'm used to it, in spite of the short sizes. But, the leg length of the pants is not 75 cm as advertised, but 78 cm. Nevertheless, it is with Gr. 20 labeled.
The pants wears wonderful, warm, and the cut is for a woman without sweeping hips very snugly. How often have I else annoyed by the "bag" on the sides! Here simply everything fits.
I can recommend the pants and would buy again despite the steep price.
Now the winter may come.
