It wasnt the only memorable costume they came up with in that back room, either.

I was fitting her for another costume at the same time it was the leather driving costume.

(A fit that would one day becomeWitherspoons favorite Elle Woods ensemble.)

Costume designer Sophie de Rakoff and her best on-screen creations.

Since their initial partnership, de Rakoff and Witherspoon have worked together time and again.

[Bradleys] just not a pink person.

Youre responsible for the legendary looks fromLegally Blonde 1and2.

Reese Witherspoon plays Elle Woods in Legally Blonde.

Whats it like styling Reese Witherspoon 20-some years apart?

We were both at very different points in our careers then.

20 years later, this is a completely different dynamic, show, and characters.

Reese Witherspoon plays Bradley Jackson in The Morning Show.

But our shorthand from having worked together on and off for so long is very, very quick.

The process has become much more efficient and streamlined, but the energy around it is the same.

WhichLegally Blondeoutfit had the most surprising story?

Reese Witherspoon plays Elle Woods in Legally Blonde 2.

I was fitting her for another costume at the same time.

I think it was the leather driving costume.

We were just throwing it together all the time.

Reese Witherspoon plays Elle Woods in Legally Blonde 2.

When we camera-tested the Jackie O outfit forLegally Blonde 2.

Reese was like, Im not sure about the hat.

I think it may be too much.

Greta Lee on Apple TV’s The Morning Show.

And the minute she put it on, that character came completely together.

The reason that costume is so iconic is because of the hat.

If you didnt have the Jackie O pillbox, it would not have the same impact.

Reese Witherspoon as Bradley Jackson on The Morning Show.

I read that Reese kept her wardrobe fromLegally Blonde 2.

Is it the same case withThe Morning Show?

She keeps the signature pieces.

The cast of The Morning Show.

Its different withThe Morning Showbecause [its] an ongoing show, so the process is different.

We hold on to stuff.

We may go back and revisit and do flashbacks.

But its a slightly different process with the show.

Who amongThe Morning Showcast was most involved in their wardrobe?

Everyone has a different process.

Reese and Jennifer [Aniston] came in with very strong ideas and continue to be actively involved.

Billy Crudup was the same.

Its always a collaboration.

[Reese will] send me a link to something shes seen or shell text me.

I saw this, or, This would be great.

Whats your favorite look you created in Season 3?

They live in a world [where] theyre on camera, which is performative.

Those three were my favorite standouts.

I noticed Bradley rarely ever wears pink.

Do you avoid the color to keep Bradley completely separate from Elle Woods?

Its always been a thing.

Theres an episode where Bradley gets outed as gay.

So we specifically did that because it worked for the character in the moment.

So we likely wont see another pink look from Bradley?

Bradley doesnt wear pink, you know what I mean?

Shes just not a pink person.

Its just not who she is.

Theyre apples and oranges.
