Season 1 starts in 1947 with a 21-year-old, just-married Elizabeth (Claire Foy). The decade following covers the beginning of her reign, the early years of her marriage to Prince Philip (Matt Smith) and relationship with her younger sister Margaret (Vanessa Kirby), who wants to marry a divorced man. (Keep in mind, Elizabeth’s father became King after his brother, Edward, abdicated to marry American divorcée Wallis Simpson.)
Michele Clapton, the costume designer for the series, said that she was attracted to the project’s complicated layers: “It was something that I was really interested in doing because of the story I had to tell, the public and private life.” In the series there were 350 principal costumes and about 7000 extras’ costumes all beautifully detailed.
Here is a video showing highlights the in the film.
In the film, the Queen is shown wearing a three strand pearl necklace. After careful viewing I noticed that the pearls were not knotted. Something only a jewelry designer would see, a very small detail. But pearls should always be knotted, the knots provide the spacing between the pearls to prevent them from touching, which can damage them.
