The blue denim A-line dress is described as long-sleeved, but the chart lists only 36 cm sleeve on L and 37 on XL. That number must be read alongside its very broad 55–56 cm shoulder measurement; a dropped seam can make the short sleeve entry misleading.

Measure total arm reach

On a dress or jacket you own, measure from the neck point over the shoulder to the cuff, then note where the shoulder seam falls. Ask how this dress’s shoulder and sleeve figures were taken. L lists 124 cm bust, 103 cm length, 55 cm shoulder and 36 cm sleeve; XL moves to 130/104/56/37. The total change is small at the arm and hem despite a 6 cm bust increase. If you are sizing up for a layer underneath, check cuff reach and hem separately.

The source names denim and a round neck but gives no fiber ratio, fabric weight or stretch. Wear it over a fine top if you want visible sleeve contrast, or alone if the selected item’s coverage works for you; neither use can be guaranteed from the chart. Blue is the only listed colour, and a current worn image would clarify the seam line.
