From the view of german market, jeans are one of the typical, permanent reminder, that the era of classic brand is looong over. Storebrand does the job for half the price. 40/50 bucks against 90/100 bucks (50 for Denim, 50 for name ).
After the jeans-crisis in the late 90s, classic brand jeans never went back to the old 90s quality.
PS:
Ok, the premium lines are of course an option.
Just like with jackets, Japan to the rescue. Japan, where quality of materials and workmanship is still alive.
