The ONC area got only about three weeks of autumn temperatures before winter set in. I follow temperatures when it comes to suit weight but calendars when it comes to color, hence the orange tie (autumnal) with a herringbone navy suit (wintry). In context, the blue-checked shirt is fairly conservative.
Tie from Paul Fredrick, shirt Charles Tyrrwhit, suit and coat JAB.
Oh, and happy Thanksgiving and safe travels.
