The boyfriend jeans are photographed in a roomy, long-legged shape that can gather near shoes. Blue and Black are selectable, with M through 3XL sizes. The source provides waist, hip and length rows, so the useful question is not simply which size label looks familiar. From M to XL the hip figure grows by 4 cm each time; from XL to 2XL it grows by 6 cm, then by 4 cm again to 3XL. That one larger step can change a comparison for a shopper near the XL/2XL boundary.

Read the uneven hip step explicitly

The chart gives M as 71 cm waist, 108 cm hip and 100 cm length. L is 75/112/101; XL is 79/116/102; 2XL is 83/122/103; 3XL is 87/126/104. Waist grows by 4 cm every row and length by 1 cm, but hip does not progress evenly. If your own well-fitting jeans measure around 120 cm at the hip, that value lies above the listed XL hip and below the 2XL hip. It does not prove 2XL will fit: the listing does not define whether these numbers describe the garment, the wearer or ease, nor does it specify rise and thigh width.

Compare a reference pair at two levels

Lay flat jeans you already like and record their waistband width at the point you wear them. Then measure around the fullest hip area using the same convention on both pairs. Ask MAXCT for flat waist and hip measurements and whether the published chart was doubled from flat widths. Check thigh and rise next: a boyfriend silhouette can look roomy in a photo while still fitting differently above the knee. The gallery does not document those dimensions or fabric stretch. The source calls the material denim but gives no fiber percentages.

After the top half makes sense, put on the reference jeans with the shoes planned for this outfit. The listed length changes only 1 cm per size, so sizing up for the 6 cm XL-to-2XL hip difference is not a reliable way to gain much hem length. The photo shows fabric near the shoe on one wearer; it cannot predict pooling on another. Ask where total length was measured from, and request inseam and leg-opening width if shoe clearance matters.

Keep color and styling separate from fit

A shorter top can leave more of the wide-leg shape visible, while a long top changes the proportion; those are styling possibilities, not fit tests. Compare the exact Blue or Black variant photos before choosing a color, and use the waist/hip reference exercise for the actual size decision. The uneven hip grade is the chart detail worth checking, but rise, thigh and measuring conventions remain necessary to make it meaningful.
