The pleated turtleneck layering sweater has a size chart with a slash in the shoulder-width column. Its 72–78 cm sleeve entries therefore cannot be compared directly with a conventional set-in sleeve measured from the shoulder seam.

Use a neck-to-cuff reference

Lay out a turtleneck you wear comfortably and measure from the side of the neck to the cuff, following the sleeve. Ask the seller for this sweater measured from the same points. M lists 116 cm chest, 72 cm sleeve and 67 cm length; 2XL reaches 128/78/73. The 6 cm sleeve progression across sizes is real in the chart, but the start point is not specified. Ask where the pleats fall and whether they change how the garment sits under a jacket.

Grey, White, Black and Sky Blue are offered. For a close base layer, compare the sweater’s finished chest with the available space in your outer garment rather than assuming the word “bottoming” means thin or compressive. The listed blend is 50% viscose, 25% nylon and 25% polyester, but there is no knit weight, collar circumference or stretch range. White opacity is also unverified.
