This year, it wasn't about how much skin, but where
we caught a peek. The keyholes came in all shapes and sizes and appeared on a variety of actresses such as Freida Pinto
, who wore an Alexander McQueen
gown with a belly-bearing cutout; and Jessica Alba
, who showed off her back in a white Narciso Rodriguez
dress. Kate Boworth
also worked the trend in an Altuzarra
number with a triangle cutout showing off one side of her midsection.
