The dress was deliberately designed to be so heavy as it was meant to represent the impending burden of Kat marrying Bastian, who she ultimately discovers was unfaithful before they exchange their vows. Caroline explained, “First, you see her get into the car, and it’s a symbol of how that wedding had gotten too big, and it wasn’t honest and has taken over her ability to see who she was marrying. “Later, you see her in the bedroom alone on what should have been her wedding night, and here she is trapped in this claustrophobic dress that’s like the concert bigger than she is. It’s the loneliest shot in the movie.” Although Kat’s wardrobe features a number of designer pieces Caroline obtained from Net-a-Porter, Versace, Neiman Marcus and Bergdorf Goodman, the costume designer also dressed Jennifer in more affordable streetwear so her character could feel “aspirational”.
