The turtleneck for cold mornings and a cardigan on top

A long sleeve mock turtleneck made of 93% rayon and 7% spandex, cut as a slim, lightweight knit. The listing describes it as suitable for wearing alone or as a thin base layer under a sweater, cardigan or jacket once the mornings turn cold.

The fabric is 93% rayon and 7% spandex, a knit the listing calls breathable, soft and high stretch. Rayon is the main fibre, and the listing says the lightweight blend drapes against the body, while the spandex is what gives the stretch for a close fit. The cut is a slim silhouette with long sleeves and a mock turtleneck, which means the collar sits close to the neck rather than folding over in a big roll.

Because it is thin and fitted, it suits the job of a base layer. The listing suggests wearing it under a sweater, cardigan or jacket in winter, and also on its own with jeans or leggings, for lounging at home, for business casual outfits and for uniforms. It is a solid color, and the listing calls it all match, though how well a color goes with the rest of your rail is a matter of taste. It comes in Light Brown, Blue, Fuchsia and Apricot.

Care is simple on paper: machine wash in cold water, no bleach, and lay flat or hang to dry. It is imported. The listing does not state the weight of the fabric, a size chart, the length, or how it holds its shape after many washes, so check the size details on the page before ordering.
