You are going to see Ms. Bassett later today in what I think is an iffy white dress, so feast a little extra on this color buffet. The underlying dress is by Ports 1961, but I don't have a credit on the coat**, which for my money -- even though the skirt is great -- is the star of this show. I would give it a full pickup and a prime-time network slot of its very own. Six seasons and a movie. And a devastating love interest.
**I do now! It's Stella Jean, and the heels are by La Silla.
She donned a super charming Moschino suit later in the day:

Perfect pattern, perfect shoe choice... she knows what the people need.
