These corduroy wide-leg pants keep the listed length at 88 cm for M, L and XL, while the waist ranges and hip measurements change. That makes hem position a separate decision from sizing up for room.

Hold length constant while comparing room

M lists a 63–73 cm waist range, 128 cm hip and 94 cm thigh. L is 73–80/130/95; XL is 80–86/132/96. The hip only increases 4 cm from M to XL, while the published waist range shifts much farther. Compare your comfortable wide-leg trouser at the waist, hip and upper thigh, then ask whether these are garment circumferences and how the waistband range was measured. A larger label may not create much extra leg room.

Put on the shoes you plan to wear and mark 88 cm from the intended waist position, after confirming whether the listed length is an outseam. White, Coffee and Green are selectable. The source calls the material cotton but does not give corduroy weight, stretch, lining or care/shrinkage data; those matter more than a seasonal label for exact hem planning.
