I asked a very similar question here some time ago, and received some interesting answers. The main thrust, though, was that USAF uniform regs don't allow for kilts to be worn with uniform items, except with very specific exceptions. My feeling is, however, in line with my fairly-newly adopted "rule of life": I'm 70 years old, I'm a veteran, and I'm Mexican; three reasons why I can say, do, or wear whatever the heck I want!
With that in mind, I recently got up my nerve, finally, and put together my gear to wear on "formal night" on my latest cruise. I'm a retired Air Force member, and obviously, therefore, not all that bucks-up, so I tried to keep the costs down, where possible. I started with a USAF tartan (Thurso) kilt from Sportkilt (the only source for any Air Force kilt I could find that was anywhere near affordable), a black (therefore outdated) mess dress jacket purchased online to replace mine, which I obtained as a cadet, and outgrew DECADES ago. The rest of the accouterments are simply items easily obtained online, from E bay, kilt providers, etc.
I think it worked out OK, and I certainly got a lot of comments, almost all of them complimentary, and was asked to pose for lots of pics! And I think I got more than a couple of guys to get into kilt-wearing...
I hope this gives your father something to think about, and, should he decide to get out his mess dress jacket, I'm sure he'll get a lot of fun out of matching it with a kilt!
By the way, CONGRATS on your marriage!!!
I'd love to send a pic, but I just can't figure out how...
