So two of my fiance's three siblings are in the military. One is going to be a groomsman and one is going to be a bridesmaid. For the ceremony are they to wear their uniforms. Personally I do not mind if they do. I am proud of both of them and if they had the choice and wanted to wear it, I would not care one bit, not to mention the fact it would save them money from buying a dress or a tux. On the other hand I would not mind if they wanted to be as the other people in the wedding party and buy a dress or a tux.
My question is are they suppose to wear it for the ceremony or do they have a choice?
