We have been invited to a wedding where the dress code is Summer Smart. Not something I’ve come across before - from Googling it we understand it’s smart and weddingy but with a concession to warm weather. I have a lovely dress and DH will wear a light suit but I’m less sure about accessories. I have a fascinator that coordinates with my dress but would that be too formal? And should DH be wearing a tie or not? Any advice would be helpful.
