The irregular-placket lace-up jacket has an eight-size measurement chart, but the closure itself is not explained. Before treating the lacing as a way to adjust fit, establish where it sits, whether it actually tightens the opening and what is under it when the jacket is worn over another layer.

Locate the closure first

Ask for straight-on and side images of the selected size with the placket fully closed, partly open and viewed from inside. Request the laced section’s top and bottom positions measured from the back neck or shoulder, plus a close-up of eyelets, ties and any concealed zip or snaps. An “irregular” front could change how the two edges overlap; the listing gives no diagram. Do not assume the laces replace a conventional fastening or that they can reduce the whole chest circumference.

Use the size ladder as a baseline

Across S to 5XL, listed chest rises from 114 to 149 cm in 5 cm steps. Shoulder width rises 45.5 to 56 cm in 1.5 cm steps; sleeve 70.25 to 75.5 cm in 0.75 cm steps. Compare a jacket you can close over your intended shirt at the same points. Ask whether “chest” is a finished garment circumference and how the asymmetric placket is aligned for the tape. A size increase changes all three dimensions, so moving up only to gain room at the lacing can shift the shoulder and cuff too.

Place the long hem

Length grows from 81 cm at S to 88 cm at 5XL. Mark both candidate endpoints on the reference jacket while wearing the trousers you expect to pair with it. Request hem circumference and a photo showing how the front hangs when seated; the chart contains neither. The source names 100% polyester and a package of one top, but does not specify lining or weather protection. White and Black are selectable. Confirm the actual closure and measurements in your chosen color and size before ordering.
