Help needed with the men's suits

We are planning on mixed peacock colours for our bridesmaids ranging from turquoise to navy, for the boys, a navy suit and my groom will wear a dinner suit in the same colour. We both really love the idea of a double breasted waistcoat, but are stumped on which colour to put him in. We are considering putting the groomsmen in paisley waistcoats and ties matching their bridesmaids' dresses, but then where do we go with the groom? I'm thinking it could look amazing or it might be a bit much? Please help!!
