People pity the poor peahen, forever in the shadow of her showier suitors, but I prefer to think she lives a life of restrained good taste in plumage of gray and brown, with a dash of blue-green (and a fun hat!). Likewise, a palette of blues, grays, and browns is a sophisticated one for humans, and intentional “peacocking” is associated with the seamy (at best) pick-up artist scene.
RT in Copenhagen would still turn all the peahens’ heads in the blue-gray-brown palette in the three photos above, where all the pieces are different but consistent in fit and tone. On the left, RT wears a tshirt under a cashmere blend cardigan with a cashmere scarf at the neck and casual gray cords. In a word: cozy. In the center, a rollneck complements trousers hemmed at a cleaner, slightly more formal length, and at right, a folk-ier style cardigan (in this case, Inverallan) is worn with a collared shirt and flat-front midgray flannels. Each combination is simple but sophisticated, with no need for pieces of flair. They’re also excellent examples of un-boring business casual (although you’d probably have to add a collared shirt on the left).
