Mother of Pearl's 'Charlotte' cardigan is so simple yet polished - it has a row of lustrous faux pearl buttons topped with logo-engraved gold-tone disks. Part of the label's thoughtfully sourced 'No Frills' collection, it's made from a ribbed organic cotton and wool-blend in a relaxed silhouette. Style it alone with skinny jeans or wear it open over a turtleneck.
