The numbered selector for the thin straight shorts looks close to an inch-waist scale, but the product chart gives a separate waist figure for every label. For example, label 32 is listed with an 80 cm (31.50 in) waist, while label 36 is listed with a 90 cm (35.43 in) waist. Use the row, rather than assuming the selector number is the exact waist measurement.

Translate each label through its row

The pattern is regular in some columns and stepped in others. Waist and hip each rise by 2.5 cm for every one-label step. The jump from 34 to 36 is 5 cm. Leg opening rises by 0.5 cm per one-label step, then 1 cm from 34 to 36. Garment length stays the same across 30–31, 32–33 and 34–36. Moving up therefore changes more than the waistband, but it does not add length at every step.

Let the tightest dimension control

Compare an owned pair of similarly cut shorts with the waist, hip and leg-opening columns. If one chart row works at the waist but is too small at the hip or opening, the larger row is the safer comparison candidate. Record how the reference garment was measured so you do not compare a flat width with a circumference.

The listing calls the type “Loose,” but the title also contains “Slim Straight.” Those words do not replace the numeric chart. The source does not explain whether the chart uses finished-garment measurements, body recommendations or a stretched waistband, and it provides no rise, inseam or measurement tolerance. Confirm those points before treating a close match as exact.

Choose color after the measurement row

White and Black are the two listed colors. Decide the measurement row first, then choose between the colors; color cannot correct a tight hip or narrow leg opening. The listed composition is 81% polyester, 17% cotton and 2% spandex, but the source does not quantify stretch or recovery.

For a repeatable comparison, the garment-versus-body guide explains why the measuring basis matters, while the rise and length guide lists the missing vertical measurements to request.
