From Jennifer Aniston 's soft gray Vivienne Westwood  Couture gown at the Toronto Film Festival and Kerry Washington in her hot pink Halston  Heritage number to Gwyneth Paltrow 's fresh-as-ever white Lanvin  dress at the Thanks For Sharing LA premiere, we were hit with some stunningly ladylike dresses this week.
