Of the options you originally mentioned, I think I like the black skirt/black shell/red wrap the best. But I think I would like it better if you could find some additional accessory in a lighter neutral tone to soften the other colors, like some sort of scarf or neck piece in cream. I wouldn't worry about "too much black" at a wedding.

Is the ceremony at the Stanley? Anywhere near Estes will be beautiful, but look out for charging elk.
