I am interested in your thoughts and opinions on this. My wedding will be in the summer, and going for earthy-tones for the wedding. The bridesmaids are going to be mismatched (they can choose any knee-length dress that fits their body and budget best, either peach or green). After conferring with a few of the groomsmen, FI and I like the idea of have them be mismatched also, with some in vests & ties, some in suspenders & ties, somewhat akin the the photo attached below (but different colors -- we are thinking charcoal gray with brown shoes). The best man came up with this idea, and I really like it. The groom would stand out as the one guy in a full suit.
However, I just talked with my parents, whom I want to respect since they are helping fund a lot of the wedding (although the groomsmen will be paying for their attire), and my father did not like the idea that the groomsmen would not all look the same. He and my mother also did not seem to think that brown shoes are proper for gray suits.
What are your thoughts? (1) Is it acceptable to have mismatched groomsmen, or is this too casual? (2) Do brown shoes work with gray suits, or should I do black shoes? And, (3), even if mismatched is okay, should I avoid it if it bothers my parents who are bankrolling most of the wedding, or go with what the groomsmen themselves prefer who will be paying for their own attire?
