I wore a black and white skirt to the posh wedding a few weeks ago. I decided to go with red jewellery, fascinator comb, shrug (M&S cropped 18 cardi, worn as a bolero, shoes (clarks flats, 5.5) and bag as I was a bit worried about the black thing in the end (was going to wear black shoes, bag and shrug). You would be fine, I'm sure. Is it very formal? I think ettiquette has always said that black shouldn't be the main colour but who says that has to be followed?
I would be happy to send anything to you if you would like?
