The costume designer on FX's American Horror Story recently revealed that Elsa Mars' (Jessica Lange) blue suit in Freak Show almost didn't happen.

Elsa's pale blue suit has become synonymous with her performance of David Bowie's Life On Mars in the season premiere. However, costume designer Lou Eyrich revealed to Entertainment Tonight that this was actually a last-minute change.

"Elsa in her blue suit, that was an example where [showrunner] Ryan [Murphy] had wanted one thing and then came to me and said, 'Nope, Lou-Lou we're going to change it up - she's going to sing a Bowie song, and I want our take on that blue suit.'" Eyrich shared.

The change was made so late in the game that they were still working on it as she was about to perform Life On Mars.

"Throwing that together was fast and furious, and literally she was walking up on stage and we were still pulling the needle and threat on it," Eyrich said, laughing. "Once it was up on stage with all the other freaks playing in the band, and contortionist leaning form the ropes, and the freaks making the little fake waves back and forth, and her riding in on the rocket - It just came together so magically that I couldn't have been happier."

This was one of the most significant scenes in American Horror Story: Freak Show, with the costume mimicking the one seen in Bowie's music video for the song.

Eyrich said that he would like to return for the fifth season of American Horror Story, though he will be working on American Crime Story: The People v. O.J. Simpson, one of Murphy's new projects.

American Horror Story returns for season 5 in the fall on FX, though the network has not yet announced a specific premiere date.
