Prince Charlie will work...but I'm partial to the Regulation Doublet myself...either is appropriate for black tie or white tie, depending on accessories. But Fluter is correct...it would have to specify civilian attire accepted. Most official functions in the military require a prescribed uniform for members of that organization. Now if you were attending as a spouse to your wife's function (assuming she was military...there are lots of dual mil couples out there...but likely not your case), then you'd have the choice to wear appropriate formal attire of your choosing.
