My groom is in the Air Force and wearing his mess dress for the wedding, and we've decided that his groomsmen (all Air Force) will wear their semi-formal blues. We were hoping that it would set him apart from the rest of the guys as the groom and it would also save some of the men from having to go out and buy mess dress. Has anyone done this or seen pictures where it was done? I like the idea of it, but I wonder how it will actually look with him in a bowtie and his men in regular neckties... is the difference in formality of their uniforms going to clash?
