You can buy many types of Ike jackets around, and few things look nicer with a kilt. I bought a Sweedish model in blue from Sportsman's Guide on the 'net, but when it came in, it was much too small for me. I gave it to a buddy who wore it to our Burns Supper last year (and a few other places) with a plain black tie, and it looked really good.

You can even buy a replica of the officer's WWII verson at What Price Glory for about 175 bucks or so, and it looks great. Shop around on the 'net, and you'll find several places that sell some form of them. Just follow the rule of thumb of ordering a larger size over the 'net.
