The pleated Henley round-neck sweater is listed in Grey and Navy Blue, sizes M–XL. Its chart gives a shoulder, chest, sleeve and overall length for each size. If you want the sleeves to reach the right point beneath a jacket, compare the shoulder and sleeve as one path rather than picking a size solely from the chest number.

Measure the reference knit in two steps

Lay a sweater you already wear comfortably over your intended base shirt. Measure straight across the shoulders, then from that sweater’s shoulder seam to its cuff. The listing gives 52, 54 and 56 cm at the shoulder and 54, 56 and 58 cm at the sleeve for M, L and XL. Both columns rise by 2 cm per size. A larger shoulder can move where the sleeve begins on your arm, so a 2 cm sleeve increase by itself does not guarantee 2 cm more wrist coverage. Ask the seller for the chart’s endpoints if your reference has a dropped shoulder or a different seam layout.

Check width and hem after the arm path

Chest is listed as 110, 116 and 122 cm, a 6 cm step, while overall length is 65, 67 and 69 cm, a 2 cm step. Compare a knit with the amount of room you like at the chest, then hold its hem against the trousers or jacket you intend to wear. If the chest points to L but the hem you prefer resembles M, the chart alone cannot resolve that tradeoff: confirm whether these are finished garment measurements and ask for a current flat-lay photo of your selected size.

Confirm the Henley details

The product name describes a pleated Henley, but the text does not give placket depth, button count, fabric composition or a tested stretch range. Those details matter if the neckline will show above another layer. The source also notes a possible 1–3 cm manual measuring difference. Request a close view of the neck and care label before relying on the placket shape or wash behavior.
