The always spot-on Penny Cruz in Versace; and, Helen Mirren, gorgeous dress, babelicious while being totally age-appropriate I'd say, in Christian Lacroix
So chic Kate Winslet in Valentino; the adorable/hilarious/maja babe Isla Fisher in Monique Lhuillier; and, Rachel Weiss, stunning, in Vera Wang
J-Lo in Marchesa:
This is Jennifer Lopez' 3rd appearance on my best-dresses list. I've certainly never considered Ms. Jenny from the Block a style icon, but apparently, to the Oscars, homegirl brings it (at least in my opinion)!
