A spencer jacket (sometimes referred to as a "captain's jacket") is also a nice alternative; it is similar to the western-style jacket mentioned here, but no western "frills".

[flame suit on] ...and with appologies to Ham...
To my eye, and this is strictly a personal opinion, the traditional PC looks martial and dated, sharp yes, but dated. How about getting a tailed tux and having a tailor trim off the tail ... kinda bring the look away from 19th/20th century military formal, and into the less decorated 21st century civilian formal; then you have the added advatage of being able to use it and kilt for the Masonic events as well (if that's permited).
No reason for a flame suit, that's your opinion. What looks good to you may look good to others, and vice-versa. I personally think the traditional PC is "timeless", and 40 years from now, when my grandchildren look at our wedding photos, my PC will still look good. As long as we respect each other's tastes, then we're fine.

A PC, though, isn't really good with regular tux trousers anyway -- far too short, save a nice pair of tartan trews, which is the epitome of class (look at Hector and Archie in "Monarch" -- but dress chuka boots are a must! :mrgreen:

I must get a pair of trews someday...
