You do seem to see more black at weddings these days I think. However, to be honest I think it's also bit shiny for the daytime bit of a wedding. You could possibly daytime it up a bit (IYSWIM
) with chunky heels (not sandally shoes) and a jacket/pashmina but you might struggle to do that successfully in anything apart from black.
It's bargainous though
. Get organising that big night out!
