This jacket is beautiful and fantastic quality. It's an American 16W which is an Australian 18. Purchased in the USA from Nordstrom. Worn once only. It has light shoulder pads and could also be worn as a dress with leggings. It runs large. Definitely an 18 and perhaps a small 20. It's fully lined with pockets (they are still stitched closed as I've only worn it once). Full zip closure. Beautifully made and great quality. I've also added two stock photos so you can see what it looks like on. The rest are my own original photos.
