Hi Suz, you look wonderful and polished in this outfit.
I too have a very similar, earlier version of this NF raincoat (mine is black). And mine is not lined. I must admit it has been serving me despite its drawbacks: crinkly, and on me the XS is very fit, maybe a bit too fit for a bulkier sweater underneath, which I always need when wearing it since it's not lined and not very warm. The other drawback is that the belt is very short. Yours look a bit longer. I like to tie my belt, like you, rather than fasten in into the snap buttons; however a shortish belt means that unless I tie it really tight it will come undone.
Despite these drawbacks, as I said, the coat has been useful mainly because of its cut and because it's a nice "feminine" alternative to gear on yucky days.
I love the color on yours, very classic, and it will go with a lot of color schemes too. I can see black, taupe, green, red, pink... AND it suits you perfectly. You look lovely in it.
