A collar changes everything a cardigan does. Without one, even a beautiful knit reads as purely casual, something you threw on for warmth. Add a collar and suddenly there is structure, intention, a sense that this is a considered outfit rather than a reflex against the cold. That is the whole argument for this collection. We have been pulling together the cardigans that carry you through winter without making you choose between warmth and looking put together. Shirt collars that layer cleanly over a turtleneck. Pointed collars that feel sharp against chunky knit. Peter Pan collars that add something almost unexpected to heavier wool. These are not transitional pieces for mild days. They are proper winter cardigans with the kind of detailing that makes getting dressed feel worthwhile when the weather gives you absolutely no reason to bother. A collar turns a cardigan into an outfit. That distinction matters more in winter than at any other time of year.
