Costume designer Erin Benach on how she kept Harley Quinn and the Birds looking fly.

I had never seen that before, that level of understanding the fashion zeitgeist in a superhero film.

Let the sartorial mayhem begin!

So it wasnt, like, a fashion show!

Great idea go ahead andtry it yourself!

That was really hard, actually, Benach admits.

That dress, I literally designed itonJurnee.

It was one of those organic moments.

Its actually very complicated, that part.

Enter Ewan McGregors Roman Sionis (a.k.a.

Black Mask), a sadistic crime lord, flashy nightclub owner, and high-functioning narcissist.

Now do you see why I had so much fun making this movie?

Benach recalls, laughing.

It should be exactly the same, but turn it into pants.

So jumpsuit it is!

Harley is like a magpie if its shiny, shes going to like it, adds Robbie.

Harleys look was like a sensory overload, which I think is appealing.

Birds of Preyis in theaters now.
