Meh... more color would be nice, she always looks like she's a widow at her husband's funeral. That first look in emerald green or red would have been great.
Absolutely hate that Dior monstrosity, utter trash, I'm so sick of tulle in gowns, they look so cheap and undone. Gorgeous necklace though.
The last dinner dress... meh forgetable. I want some full on Italian Glamour from her and this is the perfect place to show it. Call Donatella, she'll easily hook you up and make age appropriate pieces (seems she likes to be covered) or look at Alberta Feretti, maybe Ferragamo, Ermanno Scervino has nice spring pieces, even a well cut suit from Armani or Cavalli would work.
