Hi Op sorry was busy with a deadline BUT have swooped in to say I think some of our comments got you a bit confused with the gold cuff - which, I agree, you should wear. I was one of the people saying you might need gold shoes but that was because @EleanorMc67 and I are both fans of a bronze shoe, which IN THE ABSENCE OF THE CUFF I would have gone for (capitals for emphasis; I'm not shouting at you). What I worried was that unless carefully done, two competing metallic shades might not work.
BUT I think the brown suede ones that you like the shape of here work with both, especially if you go for the brown jacket. Suede has a similarly subtle effect as a muted metallic. I think the problem we were getting with gold was that to have the same tone as the cuff, they were too bright, because of the tone of gold. To me they look too light, too bright for the outfit, and having the bag match turns the focus into one, two, three focal points: the cuff, the bag, the shoes. And we want your gorgeous dress and jumpsuit to be what draws the eye, not that trio.
I think these brown suede that @RemusLupinsBiggestGroupie linked work, I think you like the shape and I think they look comfortable and will not fight with the other elements of the outfit, but have a textural aspect that works with the theme of fur, velvet etc.
You won't really see them with the jumpsuit, yet they won't cause affright if they peep out. With the dress they are back to the colour combination of that little duck. I think they work.'

That leaves us with the bag. I think, having moved away from the gold shoes, that gold clutch could work with the cuff if you love it. But if you are only getting it because it matched the shoes, then you are free to find something you love more. It doesn't need to match by any means. What about a brown suede clutch? That would be useful even with jeans and your fur jacket.
