I like the look of the pic Hamish posted. I'd probably wear the tie a bit more crisp to follow the clean straight lines of the rest of the outfit. That's just me though.

It's hard for me to see the jacket in detail on my monitor but it looks like a contemporary version of the Braemer or argyle jackets without the gauntlet cuffs and pockets and epaulletes. Avery smart and modern look but still rooted in tradition to my eye.

I'd love to put together an outfit like that for church or other semi-formal events.
