My style combines preppy, casual, and rugged elements. I tend to use selvedge jeans most days with the occasional chino. I use OCBDs throughout the year with a nice sweater when it's cold, I also wear rugbies in the fall, winter, and spring. In the spring and summer I wear knit polos and piqué t-shirts. I have lots of good jackets for my blue and earth color outfits (e.g., a Barbour Bedale, a J.Crew barn coat, a Todd Snyder quilted light blue bomber, a suede trucker, etc.). However, I don't have anything that matches well when I wear outfits that are black or grey, particularly for transitional weather. What piece would you recommend?
