The black grunge knee-buckle jeans pair wide legs with knee slits and detachable buckle belts. Removing hardware may change the look of the opening without changing the jeans’ base size. Check both configurations before deciding whether the exposed area works for you.

Fit the jeans underneath the detail

The S–XL chart lists waist/hip/total length as S 63/102/98 cm, M 67/106/100, L 71/110/102 and XL 75/114/104. Each step adds 4 cm at waist and hip and 2 cm at length. Measure a pair of wide jeans you already wear at the closed waistband, widest hip and total side length. Ask whether the listed values are finished jeans circumferences or body guidance; the source names washed denim but gives no fiber ratio or stretch value.

Inspect both buckle states

Request front, side and inside images of the chosen size with buckle belts attached, then the same views with them removed. Ask how the belts attach, whether the slit edges remain covered or open after removal, and if the hardware can be repositioned. “Detachable” confirms the belts can come off; it does not establish that they tighten the leg or close the slit.

Locate the knee opening

On the reference jeans, measure down from the waistband to your kneecap while standing and sitting. Ask for that distance to the top and bottom of each slit, plus front rise and inseam. Overall length of 98–104 cm cannot locate the knee detail without rise and slit measurements. If the buckle placement matters to you, compare its height after matching waist position rather than matching only a photo.
