My wedding colors are robins egg blue and ink blue (maid of honor's dress has a white top with ink blue skirt and robins egg blue for everyone else) Our wedding will be listed as business casual on the invites, we are having a morning wedding with brunch following. I had envisioned the groom to wear charcoal slacks and vest and a navy sportcoat and necktie with a robin's egg boutonniere but now i am questioning if that will look ok with the color scheme. My dress is slightly grayish white. WDYT?
