A fine ribbed cardigan with a frill following every edge: around the round neckline, down the length of the button placket, at both cuffs and along the hem. The ruffle is small and closely gathered rather than showy, so it softens a plain knit without turning it into an occasion piece.

The rib itself is fine and elastic, which is why the shape holds so close to the body. It buttons all the way up to the neckline, and the cropped body stops at the waist, so it sits neatly over a high-waisted skirt or trousers and finishes exactly where a waistband begins. It is unlined, which keeps it light enough to wear indoors all day. Worn open over a vest or closed on its own, it works as the single thin layer for a cool office, a crisp autumn evening or a heated room in winter. The rib recovers its shape after a day of wear rather than bagging at the elbow.

Sizes run 4-6 / S to 20-22 / 2XL. The fit is slim and runs small, so size up if you would rather it sat away from the body. Our model is 5'6" and wears size S. Machine wash cold or have it professionally dry cleaned.
