Retiree in Uniform for BCT Graduation; yes or no?

AR 670-1:

Chapter 21
Wear of the Army Uniform by Reserve, Retired, Separated, and Civilian Personnel
21–1. Occasions of ceremony
a. 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, weddings, military funerals, memorial services, meetings, conferences, or similar functions of associations formed for military purposes, of which the membership is composed largely or entirely of current or honorably discharged veterans of the Armed Forces of the United States. Authority to wear the uniform includes wear while traveling to and from the ceremony or function, provided the travel in uniform can be completed on the day of the ceremony or function and must follow guidance included in paragraph 3–7c.
b. All persons wearing the Army uniform will wear awards, decorations, and insignia in the same manner as prescribed in this regulation for active duty Soldiers. For civilian attire, individuals may wear only those awards, decorations, or insignia authorized by this regulation for wear on civilian clothing, in the same manner and approximate location as the equivalent military uniform.

Soooooo.....wear it up and just wear it correctly.

Absolutely wear it as long as it fits and you follow the regulation. You can wear the one that was approved when you retired or you can get a new one.

AR 670-1, Chapter 23 authorizes and establishes guidelines for wear of the uniform by reserve, retired, separated, and civilian personnel. Chapter 13 covers the dress uniform.

For more specifics, DA Pam 670-1, Chapters 11 and 21 are where you want to look.

If you google the AR or DA Pam, the first link is to a PDF from the army pubs. Anyone can click it and pull it up.
