I'm not sure if you Ground Pounders had a similar uniform, but the Air Force has what is called a Mess Dress Uniform. White short (waist-length) jacket with epaulets, braid and gold buttons. Dark blue or black trousers with satin stripe on the outer seam. White shirt and black tie, and a cummerbund.

If you can find one, it would look good with a kilt, either left white or dyed a color to co-ordinate with your kilt
