`Say Yes to the Dress' returns to one of the world's premier bridal salons, Kleinfeld Bridal in New York City, for `Big Bliss', an emotional journey for plus-size brides as they shop for not only their dream dress, but one with a perfect fit. The latter is not always an easy task for women who have struggled with weight issues their entire lives, but the Kleinfeld staff goes to sometimes extreme lengths to find the dress that matches each bride's personality and body type.
