The featured Khaki image of this washed baseball-collar short jacket shows a ribbed hem ending above the hem of the black shirt underneath. That visible shirt edge is the outfit’s useful reference point. If you want a similar layered look, decide how much shirt should show before treating the jacket’s overall size as the answer. The listing also offers Black, but the Khaki image cannot establish the Black shade or finish.

Place the two hems before choosing a size

Put on a shirt you already own and mark where it ends. Then place a short jacket over it and check whether the difference between their hems suits you with the jacket open and zipped. A shirt that extends below the ribbed hem creates the contrast visible in the featured outfit; a shorter shirt leaves the jacket edge as the lowest layer. The image shows the jacket partly open, so it does not prove how this exact item drapes when closed. Our shirt-and-jacket layering guide gives a broader way to check the same placement with your own clothes.

Use width and length as separate decisions

The listed chest figures are M 120 cm, L 126 cm, XL 132 cm and 2XL 136 cm. The matching back center lengths are 60, 61.5, 63 and 64.5 cm. From M to 2XL, chest changes by 16 cm while back length changes by just 4.5 cm. Sizing up can add substantial width without moving the hem much lower. Shoulder widths rise 54 / 56 / 58 / 60 cm, while sleeves are 58 / 59 / 60 / 61 cm. Compare all four dimensions with a jacket that fits over your intended shirt.

For example, if your reference jacket measures 124 cm around the chest, the L row is 2 cm larger, M is 4 cm smaller and XL is 8 cm larger. Those differences are arithmetic, not a predicted fit: the source does not define every measurement point, and it allows a 1–3 cm manual measurement difference. Ask for the exact chest-measurement method if two rows seem close. The model reference is 172 cm tall and 56 kg wearing M, but those two body figures cannot replace your own garment comparison.

Confirm the fabric and finish

The source lists 100% cotton. It does not provide fabric weight, care instructions or a shrinkage figure, and “washed” does not establish how the jacket will change after laundering. Ask for a close view of the fabric and the care label if those details matter. The featured photo shows a front zipper and a small chest zipper, but their storage capacity and durability have not been tested here.
