It's been milder the past few days but the low point of my trip to New York last week occured when I exited the terminal building at JFK into near-freezing temperatures with wind, spitting rain and about a hundred people ahead of me in line for a taxi. Fortunately, I'd packed a tweed topcoat or I might not have survived the experience. Tweed sheds moderate amounts of rain and that makes it an effective covering in anything short of a torrential downpour.
The following day was warmer and my luncheon companions and I made do with 14 ounce flannel suits (I wonder how often three heavy flannels occur without prearrangement at the same table in Manhattan). But in my wanderings around the city I spotted two best of class coats that I'll be reporting on tomorrow and the next day.
Coat season has begun.
