May I suggest you consider THIS jacket, which is German army tropical tan?

Buy two of them and cut one of them down to either an Ike style or to more of an Argyll cut. Thompson's book shows conversion of a similar tunic. Save the second one in case of a disaster or a better styling idea. I recognize this is polyester and won't be quite as nice as actual USGI tropical wool, but I think it might give you something of a compromise between your desire to wear something with a military flair and your need to avoid violating the regs. By all means, change the buttons. Somebody else will have to advise about wearing medals and decorations.

What say ye?

For my nickel, I think khaki is perfect for a summer wedding.
