I've worn this jacket a couple of times now, and even though it works with many colors I have to admit blue fits it the best. Here's something from last weekend.
Items include a Paoloni light brown flannel odd jacket, white spread collar shirt, light blue cashmere vest from Banana Republic, darkish blue Incotex chinos, split toe derbies and a navy paisley pocket square.
Love how the jacket fits, having just enough room for a lightweight vest too. The white shirt keeps the look fresh and simple.
The pocket square is from some Italian brand, bought from St. Petersburg by my sister some years ago. A nice touch here I think, as the light blue in the paisley patterns compliments the vest in a beautiful manner.
The Loding split toe derbies are both dressy and casual enough for the outfit. A double monk pair I have coming in from Meermin would work here as well. The socks are ribbed thick cotton and light blue.
And, I had my peacoat on to stay warm. I was against wearing it with these chinos at first, but after some thinking I didn't really care about them being navy and darkish blue. Enough contrast for it be worn as an overcoat and that's that.
