The Rosie is a perfect throw-it-on-when-you're-cold-because-it-goes-with-everything sweater. It'll even go with nothing — we love the way a cardigan looks worn as a shirt. This one is made from a buttery-soft cotton/silk knit plaited with elastane (meaning stretch yarn is actually knit into it) so that it hugs the body without feeling tight or overly slinky.
