My fiance is AF and last night we were talking and he made a comment about needing to purchase a mess dres uniform for our wedding. Our wedding is not going to be super formal so I did not see a reason why he would need to get one. He was under the impression that he HAD to wear it for some reason. As far as I know we do not HAVE to do anything for our wedding and I like his service uniform just fine. What do you all think about this? Does he have to wear his mess dress?
