Thanks, Mimo - were anyone to like the two-toned shoes, I knew it would be you.
New & Lingwood make all of their suits with working sleeve buttons in that particular configuration - two and two. Dunno why. The shoes and the suit were impulse buys, but seemingly, they were good impulses.
I hadn't thought to look for an olive suit, but the color does seem to complement my own coloring - a very happy accident. Thanks!
