Ladies Monsoon Long Purple Silk Gown Dress 12-14

Ladies' Monsoon one shoulder ballgown evening dress in purple silk. The size stated is a 16 but this dress is about ten years old and the sizing is way out. The dress is more like a 12-14, but please go by my measurements: 44cm across the bust, 40cm across the waist, 124cm down the side with no shoulder strap. Good preowned condition apart from a dark mark as seen in the photos. This is not really noticeable but mentioned to avoid disappointment.
