The washed denim jacket lists an 88.4% cotton, 11.6% polyester material and four measurements across S–2XL. To choose a row, lay a jacket you already like flat and record its chest, shoulder, sleeve and total length using the same points. A single chest comparison can hide a shoulder or hem change that matters more to your outfit.

Compare the M and L rows as a complete change

M is listed as 112 cm chest, 51 cm shoulder, 53 cm sleeve and 68 cm length. L is 116, 53, 54 and 70 cm. Moving from M to L adds 4 cm at the chest, 2 cm at the shoulder, 1 cm at the sleeve and 2 cm at the length. Write those four differences beside your reference jacket. If the chest favors L but the shoulder and hem already match M, ask for a finished flat measurement or a photo rather than assuming one larger row solves every dimension.

Test the reference layer, then verify measuring points

Compare the jacket over the top you expect to wear underneath. With your own reference jacket, note whether the hem covers that top and where its shoulder seam sits. The source says the garment was measured flat and allows 1–3 cm manual variation, but it does not diagram the chest or sleeve endpoints. Ask whether chest is the full circumference, where the shoulder is measured and whether length starts at the collar seam. Those conventions can change the comparison.

Use the model note only as context

A model note gives 172 cm height, 56 kg weight and size M. It does not provide that person’s chest, shoulder or preferred layer, so it cannot replace the four measurements above. The listing does not document shrinkage after washing or wear-tested room. Confirm the care label and finished dimensions if either affects your decision.
