Even when ordering the pants for my wife it was clear that the information given in the graph to the length of the pants are unlikely.
My wife is 172cm tall and has a girth of 90 cm (one size 45cm).
To get an exchange before we ordered the size L (specified width at the waistband to 49 cm) and XL size (specified width at the waistband to 52cm)
Both pants - sizes were too small for my wife and therefore go back!
Remeasured at the size XL is a maximum waist size was 46 cm (elastic stretched). Length pants with waistband 108 cm.
In the interests of other clients it would be good if the seller corrects its size.
