Tweed Odd Jacket as a DB?

Why not, this is not a sober example anyway.

Not my taste.

To each his own, I suppose.

I don't think DBs go well sans tie, at least not in the traditional manner. Are you going for the double-breasted coat with turtleneck look like Label King?

I dressed in costume as a louche European aristocrat yesterday, for a photo project. Wound up wearing a 4x1 DB jacket with a J. Press buttondown collar shirt, no tie. It worked well enough for me. You'd also want to tread carefully in terms of checks -- I think most checks look better on SB. I think a light-weight herringbone tweed would be choice, or a donegal in a slightly unusual color.

Everyday that passes on this forum, I fall further and further behind the curve.

I think you are asking two questions:

1. Can tweed be used for a DB?
2. Can you wear a tweed DB w/o a tie?

I think for (1) there is historical precedence and the example you show seems no more radical than a slubby linen or wool DB so why not. For (2) any jacket can be work w/o a tie BUT should you? Since the traditional shirt for a tweed w/o a tie is a OCBD you would be wearing a BD with a DB. Again - certainly possible but it would violate a basic rule.

Finally - the jacket looks slightly feminine - the combination of the shape and colour (or flash?) combined with 4 button stance. Nothing wrong with that if you are comfortable with it.

Not a fan of DBs without a tie, tweed or no.

Not to my liking but each ti their own.

Tweed DB, yes. DB with no tie, no thanks. I did it once and will never do it again.

I think a DB without a tie looks queer, somehow.

With regards to the DB in tweed -- http://www.styleforum.net/t/140983/double-breasted-tweed-sporstcoat

However, that coat in your picture looks quite good.

Check it out...white Brooks BD and white hanky...happy now, smart guy*?

The car shot, I think, is more iconic.
