It’s not for everyone—Tom Ford is on record as hating the look—but Spencer knows how to pull it off better than anyone.
You’ll want a smaller collar than usual and a thin knot to keep everything roughly in proportion, but the real trick is leaving the top button unbuttoned. The jackets in question are usually three-buttons, and fastening the top one is every bit as bad as fastening the bottom.
And if you want to throw in a quick lapel trinket to show off how clever you’re being, we’d say you’ve earned it.
