The Netflix hit’s season 4 wardrobe is to Di for.
She just kind of looked ordinary.
You know, bobbly old cardigans and jumpers and skirts a bit dumpy, really.

(Corrin agrees: I was like, are you joking?)
Her look evolves a bit when she moves to the palace, but it still wasnt quite her.
It was a little bit old-fashioned and safe, Roberts observes.

Wryly titled Fairytale, the episode invokes the popular conception of Diana as a sort of doomed Cinderella.
Ben Caron, our director, had always imagined it like a Cinderella story.
And then it sort of culminates in the wedding dress.

Its almost like a big Walt Disney fantasy, that dress.
Its not an absolutely spot-on copy of it, Roberts clarifies.
Its closing your eyes and thinking, What was that dress like?

And it was big sleeves, wasnt it, big puffed sleeves and that big skirt.
While some costumes onThe Crown like uniforms and ceremonial pieces demand accuracy, theres a mixture, Roberts says.
Im a big believer in making a big nod at it.

It was like designing a dress-up dolly look for each occasion.
I always felt very much at the beginning thats what we were doing, for her.
You feel shes growing up a bit, Roberts says.

Her unlikely fashion foil is all grown up, however, and dressing with intention from day one.
I found that absolutely extraordinary how her journey, and her clothes, developed, Roberts says.
As her strength grew, so did her shoulders.
In a way, it was like putting on her armor.
Her final appearance is her fiercest of the season.
The first time you see Diana [is] as that little elfin fairy creature.
That, to me, sort of sums Diana up in season 4.
Season 4 ofThe Crownis now streaming on Netflix.
