I have size 48 and therefore ordered in size 48/50. The quality of the delivered trousers would not be amiss - but I have seen at first glance that they can not fit me. Tentatively hatched in one leg and stuck already at the calf.
Gave it to a girlfriend - she has size 38/40. My pants fit like a glove. Pay nothing for sale at the manufacturer. So stay away if you can work out that in the offer size (minus 10) is present kwin fitting part.
