The Duchess of Cambridge owns this ribbed turtleneck sweater from the Danish designer Mark Kenly Domino Tan. It’s the Karlotta ribbed turtleneck sweater in ivory.

We first spotted her wearing it in Copenhagen, Denmark in February 2022. The Duchess chose the cosy knit for a visit to a Forest School.
Update: On an earlier version of this page, I shared an ID that turned out to be wrong. Kate’s sweater was incorrectly identified as H&M. After further analysis, it looks like she’s actually wearing this piece by Danish designer Mark Kenly Domino Tan. Apologies to anybody who purchased the H&M version in good faith.
