29.1 Occasions of ceremony
As used in this regulation, the phrase "occasions of ceremony" means occasions essentially of a military character at which the uniform is more appropriate than civilian clothing. These functions include but are not limited to military balls, military parades, military weddings, military funerals, memorial services, meetings and conferences, or functions of associations formed for military purposes of which the membership is composed largely or entirely of honorably discharged veterans of the Armed Forces or of Reserve personnel. Authority to wear the uniform includes wearing the uniform while traveling to and from the ceremony, provided the travel in uniform can be completed on the day of the ceremony.
