EXCLUSIVE AT NET-A-PORTER.COM. Roksanda has been proving how elegant statement sleeves can look since launching her iconic 'Margot' dress five years ago. Previously designed in a bell shape, they've evolved into a sculptural petal silhouette. This piece is cut from blush crepe with a neat nipped-in waist and flared skirt. It's perfect for all those spring weddings and christenings beginning to pop up in your diary for next year.
