Best man wants to wear his navy dress uniform. Groomsmen and FH will be in a tux. FH is okay with it and thinks it's pretty cool actually, and seems okay with the fact that he won't be the one looking special on his wedding day. I want to let it happen but I'm nervous that it'll look odd for one member of the bridal party to look considerably different from the others.

Has anybody seen this work out nicely? I'm just worried I'm going to look back at my pictures and cringe, and wish I had said something, but I understand there's a lot of pride in a position like BM's. And I don't want to argue too hard on something FH is okay with.
