Margaret's casual look was inspired by Audrey Hepburn's style on-screen. She wears a goldenrod sweater by Dries Van Noten, black cotton-linen pants with gold buttons at the hems, a grey and white striped shirt and scarf by J. Crew completed with black ballet flats.
Margaret wears Gammy's wedding dress for her wedding to Andrew. Two dresses were made for the movie - one which was bigger, as Grandma Annie had been pregnant when she wore it, and one that had been tailored to Margaret's physique.
The dress is ivory 4-ply silk charmeuse with dolman sleeves. There are buttons down the back and at the sleeves, with a smocked diamond shape design below the chest.
