Stella McCartney Sierra Stretch-Crepe Dress

Stella McCartney's 'Sierra' dress is the kind you'll be reaching for time and again for all sorts of occasions, whether that be a work conference or last-minute wedding invitation. Cut from comfortable stretch-crepe, it has a T shirt-style top that tapers at the waist and a softly flared A-line skirt. Box pleats at the hem are framed with slits that open as you walk.
