If you could only get 1 jacket MTM, what would be your "oneJacket" that could work in most occasions? Casual, social, work, etc. I think Navy solid is too generic. Maybe one detail to add SOME flair, like a subtle check, or purple pinstripe, etc. Worsted wool as its too suit/formal looking. Well, I think you have a few options. First, I would stay away from any stripe or check. It would automatically make the jacket not work with anything but a solid pant. Secondly, for navy, I would do a heavy hopsack weave. Hopsack is porous enough to breathe when its warmer out, but ina heavy weight also wearable in colder temps (I'm wearing my Navy hopsack today, and its freezing!). But Navy sometimes can come across as dressy, too dressy in some circles. If this is what you decide, brown horn buttons should be the way to go. What I think would be your ideal choice however would be a lighter weight (think 10-11 oz) tweed in one of the following colors - brown, blue or grey. You could do either a donegal or a subtle herringbone, of which I think a donegal would be more versatile. Donegal could be worn with any pattern or color, especially if there are lots of different specks of color in it, as there are in many donegals. The weight would make it ideal for year round use, and honestly the only thing it would NOT work with MAY be very dressy trousers. You could do this with khaki, wool, jeans, checks, plaids and could use many shirt tie combos as well. Hope that helps, and good luck. As usual, solid advice from NYR. Your thoughts?
