My fiancee and I disagree over this issue. I'm only having one groomsmen (I have a lot of close friends and didn't want anyone to feel slighted and my best man had the same problem, so we both agreed to just do one for both of our weddings). I essentially think all the tuxes should be similar, but that only the fathers need to be the same (and all the groomsmen, were I having more than one). Additionally, mine can be different than either of the preceding classes. My fiancee, who I'm afraid is right, insists that all the tuxes should match, with mine being the only one where variation is permitted. Any thoughts?
