This is US 28 raincoat. It would probably fit 3x-4x. I got it on Simplybe which is no longer around. It had a removable insert that was so itchy and uncomfortable that I threw it away. (I didn’t know I was going to sell it) the coat itself is very warm but you could buy a new insert or wear layers. I mostly used it as a raincoat! It’s very warm on its own and has a very nice hood!
