Katie Holmes attended the premiere of new miniseries The Kennedys in Beverly Hills yesterday wearing an eggshell-blue knitted sundress from Ralph Lauren's spring 2011 collection. She paired the dress with beige strappy heels and a gold necklace bearing a pendant with the letter S carved into it.

How do you like the casual direction of this outfit for a premiere event? Should she have dressed it up — and how?
