At a table scene with Katherine, Nancy and Bill during Betty's wedding reception, Nancy walks into the scene twice to see if Katherine wants anything to drink.
At the wedding, champagne is served in flute glasses, which were not popular and rarely used for champagne until the 1970s, when drier vintages became preferred; instead the champagne coupe (or saucer) glass was almost universally used for serving the beverage in the 1950s, and still is in champagne fountains at weddings.
