In a video shared by FX on their official YouTube, fans get a behind-the-scenes look at the fashion of "AHS: Hotel." Costume Designer Lou Eyrich shows viewers what she calls "The Gaga Room."  Lady Gaga herself shares that she and Lou worked "really closely together" on The Countess' fashion, with designers who previously worked with Gaga sending in pieces in the hopes of them making the production. However, the final costume choices came down to "AHS" creator and showrunner Ryan Murphy, who looked through "hundreds and hundreds" of outfits pitched to him by both Eyrich and Gaga's teams and then handpicked a staggering "50 to a hundred gowns from each batch," as Gaga tells FX. Lady Gaga also loaned the show some gorgeous Versace pieces from her personal collection. 

On her character's sartorial choices, Gaga shares, "The Countess is an extremely complicated character. Lou and I spent time looking at the clothes, reading the script, and talking about how I feel about the character. Because fashion is such an important part of my life, it's hard for me to put clothes on for no reason."

The team's meticulous efforts certainly paid off, with The Countess' looks being one of the highlights of the show. While Lady Gaga isn't slated to appear in any upcoming "American Horror Story" seasons, we imagine any return of the actress would be full of equally incredible fashions.
