From the pattern:

“Aptly named, Norah’s cardigan begs to be worn any which way you choose - right-side up or upside down and inside or out as either a long hip-hugging jacket or a short jacket with a generous shawl collar. Crocheted seams combined with Norah’s wonderful and generously textured reversible stitch pattern play a significant role in why the cardigan can be worn so many different ways.”
