Colleague's wedding in a few weeks actually a civil partnership ceremony, but quite big and fancy, I think and this is what I came up with when I went shopping this week. (A rare event - 2DDs at home :)

It's not as short on me as on the model, and I do like it, but I'm not sure it's right for a wedding and don't know what to wear it with. Am ridiculously klutzy and could never pull off serious heeled boots as in the picture, tho I do like the idea of boots. There's no way to add a belt for color. A bag?
