If I am remembering correctly, Joanne seems to make bigger wardrobe splashes here and there than the others, possibly because her costumes on the show themselves are -- by necessity -- very plain. So this is her chance to be like, "See? CHECK IT OUT." And indeed, she looks great.
Michelle is beautiful, and the dress is perfectly nice, if a tad snoozy. But her need isn't as great. We've gotten to see her in period finery for three seasons now.
Classy as always, if perhaps a tad wintry. I LOVE the jacket and the hint of sexy cleav. And the lipstick. Her coloring is so great. I always wanted that coloring, ever since I read the Caitlin Ryan trilogies by Francine Pascal. Never mind that the cover model for each trilogy always looked a) totally different from each other, and b) totally different from Caitlin as described. My copy of the first one had a blonde Yasmin Bleeth on it, for crying out loud. And she isn't even a blonde normally. ANYWAY.
Mrs. Hughes, you are a vision from the neck up, and that color on you is wonderful, but in essence you are wearing a Woods of Windsor pot pourri bag.
Thomas! Your hair! Is that a spoiler of some kind?
