Coming up with the right look for Harley Quinn in "Suicide Squad" wasn't as simple as throwing on Harley's classic jester costume. The process was actually a bit more involved, as director David Ayer and actress Margot Robbie recently explained to Yahoo! Movies.

"Every variation that Harley could wear, I tried it on." Robbie explained about the evolution of Harley's costume for the film. "And, in the end, it was kind of overwhelming. We weren't sure which direction to go in. I didn't feel like we really found that thing yet." It wasn't until costume designer, Kate Hawley, showed Robbie an old picture of Blondie lead singer Debbie Harry that inspiration finally struck. "That's bad ass." Margot replied when seeing the old photograph. "Let's do that."

Ayer backed up Robbie's remarks. "You know, we tried on all sorts of different versions of the costume, tried on a jester version of the costume that so many people are in love with, you know that's part of the fun of this, is really finding out, you know...what looks great on camera."

Along with Debbie Harry, Ayer looked to more recent times to round out Harley's look. "I took inspiration for the current Harley Quinn costume from the New 52 series. And I really wanted to stay in her primary colors of the red and blue." Which, would also end up including Harley's "infamous" hot pants. "It's kind of her standard uniform in that iteration," Ayer continued. "And Margot rocks 'em."

"Suicide Squad" is in theaters now.
