For shirts go for blue including blue chambray. I particularly like blue denim shirts with a wool tie and khakis with donegal.
Brown leather or suede shoes or boots and a belt.
It's a brown, tweed jacket. You can wear one with damn near anything.
And yes, OP, a brown donegal tweed jacket would be a very good addition to any wardrobe. Man or women, old or young, casually dressed or professionally dressed. It'll look good with a tee shirt and jeans (well, not to the eyes of many here, but a normal casual look these days), and it'll look good with wool trousers and a tie.
