I am looking for a few tweed jackets and waistcoats on Ebay. As this is my first time buy a jacket to wear with my kilt, I am a bit nervous about buying the right thing. Its a bit overwhelming for this newbie.

90% of the time I will be wearing it during formal nights on cruise ships. My wife and I both work as Sign Language interpreters on the ships. While most of the other gentlemen on the ship that are kilted will probably be wearing a Prince Charlie, I won't be able to pull that off. My job requires the jacket to be rather plain, so the flair that usually comes with the PC won't work.

So, my question is, what search terms should I be using when looking on Ebay? I don't want to buy a jacket that needs to be altered to a wear with the kilt. Thanks for helping me out in my Ebay search!
