The weather is fine right now, the temperature today was in the 50's F. So the only real question was what would be appropriate dress? We've been to this home before, and seen other guests in jacket and tie, jeans and sweaters, and so on. Plus, it wasn't clear if this was a sit-down dinner or a drop in, running buffet.
So, I went with this:
Duck Head chinos, alligator belt with turned silver buckle, Bass Weejuns, cashmere roll-neck from Orvis, J.Press olive herringbone sport jacket, and the 1950 rose gold Omega bumper caliber 332.
At the time it seemed a solid choice: casual but refined. When we arrived, the hosts and most of the other guests were wearing jeans and sweaters. Good: It's better to be a little overdressed than a little underdressed.
The cashmere roll neck was a bit warm while we were all standing around the kitchen noshing. But by the time we got to the table for the dinner, it was fine. All in all, very comfortable kit for a lovely evening.
