I had a Brooks Brothers herringbone almost exactly like this. Size 41L. Mid-60s. Half-lined. Lost it in Heathrow Airport, running for a flight, carrying my baby son and all our luggage. I started sweating, so I took it off and draped it over my shoulder bag. Slipped off in the tunnel between terminals.
One of the saddest material losses of my life.
