The brown jeans list five sizes with three useful figures each: waist, hip and full length. That gives a better starting point than the name “Problem Child,” which says nothing about fit. For example, S lists 64/104/100 cm and M lists 68/108/101 cm in that order.

Compare waist and hip together

Measure the finished waist and hip of jeans you already wear comfortably. If that reference pair is 66 cm at the waist and 100 cm at the hip, the M row would differ by 2 cm at waist and 8 cm at hip—if the listing’s figures are finished garment circumferences. The page does not state that convention or the rise, so this arithmetic is a comparison worksheet, not a size recommendation. Ask how the waistband and hip were measured on a laid-flat pair and request a rise measurement.

The listed length moves from 99 cm at XS to 103 cm at XL, while the size selector offers Brown only. Compare that outseam with a favourite pair while wearing the shoes you intend to use. “Denim” identifies the material category but not fiber percentages or stretch; request the sewn label and relaxed versus gently extended dimensions if give matters.
