Waisting Away: We've long wondered why Rachel McAdams isn't a bigger star. She has the looks, talent and dimples to make a grab for the America's Sweetheart crown long ago abandoned by Julia Roberts and Sandra Bullock. So what if she's Canadian. Her adorableness crosses borders; just ask the army of "Notebook" fans who pray daily at their Noah and Allie shrines that she'll rekindle her twice-fizzled romance with Ryan Gosling (hey, don't look at us, we dismantled our altar months ago). Not that you can measure the actress's many charms in this spacious, leg-o-mutton-sleeved striped shirtdress. Good rule of thumb: If you have to use your hands to highlight the spot where your waist used to be, find another outfit. Also not helping matters is the figure-erasing frock's deep blue hue, which, while lovely, washes out the peaches-and-cream complexioned actress. And the news is equally dire for Rachel's undainty, cutout heels, with her enviably shapely legs paying the ultimate stumpy price for her open-toed footwear folly.
