When the trousers then arrived, and I tried them on my puzzled face came to light.
The trousers were, although a larger number (W34 W33 instead as the 507) ordered,
waistband too tight, I got this the best will not be!
It was a sensation W31 / L36!
Have returned the pants, and again ordered the same thing in W36 / L36,
This fits perfectly!
About the build quality I do not need to review, this is Levi's typical 1A.
Long story short:
someone else might get lucky, but for me, unfortunately the pants fell out much too small!
Therefore, only 3 out of 5.
