[...] in order to avoid the accumulation of two hats, I went bareheaded to the office and re-used the one there, trusting that the brown hat with grey suit combo could work - not as harmonized, and would have worked better had I thought of using some reddish-hued, or other appropriately selected, complement, to bring it all together, but I do not think it turned out badly after all for a "patch"...
I have always liked the look of a dark brown hat with a light grey suit.
