Well, first of all, thanks to those of you who said I wouldn't be out of place with dressy slacks. Here's my comments: On my first evening I wore the black Eileen Fisher crepe slacks, pale grey silk tank, black Eileen Fisher jacket, dressy patent leather ballet flats and pearl/sterling necklace. I was one of the better dressed ladies in the room (in my own humble opinion). There were some other lovely outfits, but overall I was surprised at how casual most women were. As Monday night was very chilly I went ahead and wore a cashmere sweater set and grey wool slacks and brought a cashmere shawl to stroll on the porch. Again, I felt comfortable and classic. I'd say the split was 60% pants and 40% dresses/skirts. There were several large tour groups in the hotel and they tended to be the most casually dressed. Private business groups were also there and tended to be dressier. I did see the most adorable girls, around 12 yrs. old wearing pretty dresses and fascinator hats in their hair.
