I have a wedding next month and want to take my new Corneliani tux out for a spin. The groomsmen are all wearing the classic black tux/black bow-tie combination which precludes me from doing the same. I thought about just doing it, but asked the groom and he said the tux is fine but to avoid a bow-tie since that is how he has his groomsmen dressed. I searched around the forums a bit and much of what I'm reading is that a tie with a tux is no good. The invite actually says 'black tie optional' which makes me think I should be allowed to just go with the classic black bow-tie look as I had planned. Should I press the groom on this? It is his day so unless I'm 100% correct then I'd rather not. Thank you gentlemen for any advice on this matter.
