A black suit would be fine, then?
You're not trying to get me in trouble, are you? Â In case you missed it, I am on record at torturous length ranting against black suits. Â No black suits. Â Dark blue or any shade of gray. Â I would stay away from stripes and plaids, but they might look OK if subtle enough.
So the Godfather doesn't typically wear something different from the other attendees, correct?
I don't think there is a "typically" in this case. Â Christenings or baptisms used to be only slightly less formal than weddings. Â Whereas the groom, groomsmen, and father of the bride would wear morning coats to weddings, papa, grandfathers and godfather would wear strollers to christenings. Â But mores have ... evolved. Â Contrary to my reputation, I am actually aware of this. Â The stroller is for all intents and purposes dead. Â Therefore, I recommend trying to approximate its look as closely as possible. Â If we were to be real sticklers about it, we would rule out the color blue, no matter how dark. As for wearing the same or different things: formal day wear didn't used to be so uniform back when people owned their own stuff. Â Men were just presumed to have the right jacket, shirt, tie, etc., and to know what was appropriate and show up correctly dressed. Â So everyone would look largely the same, but a little different. Â Sort of like black tie today: everyone's in a DJ (theoretically) but different cuts, models, shirts, etc. Â Matching kit appears to be an invention of the rental industry. By the way, I don't know where you live or how your friends dress, but chances are, if the godfather shows up in a nice gray suit, white spread collar shirt, and Macclesfield tie, he WILL be wearing something different from the other attendees.
Any advice about the toddler-recipient? Â A suit? (for the US baptism)
Oh dear. Â No, I don't know. Â I hate to advise you to to buy something that will be worn once and fit for less than a couple of months.
