Lena Dunham is in her Reputation era. The 38-year-old writer and producer supported her friend Taylor Swift at the London Eras Tour in an outfit that not-so-subtly nodded to the singer's 2017 album.

In a Monday, Aug. 19 Instagram Story post, Dunham shared a mirror selfie showing off her concert outfit, which consisted of a black bodysuit with the word "trash" written in rhinestones, a black maxi skirt and black handbag.

"Was in my rep era for @taylorswift at Wembley- have seen her over a dozen times and each one more magical than the next," the Girls creator wrote over the snap. "Didn't even get more pics because I was dancing til I sweat through this bodysuit. #erastour for infinity."

"And yes the top says TRASH cuz... yeah," she added.

Dunham tagged the brands she wore including Namilia which makes the Crystal "Trash" Bodysuit. The star revealed her skirt is by My Mum Made It and her bag is by Medea.

Dunham's All-Black Look References 'Reputation' Era

Dunham's all-black look references Swift's sixth studio album Reputation, perhaps fueling the rumors that Reputation (Taylor's Version) is coming soon. The album is next up in Swift's re-recordings of her discography and the singer has been seemingly dropping hints at an the re-release. At London's Aug. 17 show, she used a snake-like motion to wave goodbye as she descended into the Wembley Stadium floor, per concert footage shared on X (formerly Twitter). Additionally, the show occurred on the seventh anniversary of when Swift wiped her socials clean and first teased that Reputation was coming.

Dunham's 'Protective' Friendship with Taylor Swift

Dunham and Swift have been friends for over a decade. In a recent interview with The New Yorker, the Catherine Called Birdy director said she was "protective" of the singer. "I’m always very careful to be protective of her in every single way," she explained. "Probably the two things I get asked most in life are 'What is Taylor like?' and 'Can I have tickets to the Eras Tour?' And usually my answer to both things is no." Dunham also shared that Swift is "everything that you would want her to be." "She’s kind, she’s devoted, she’s introspective, she’s emotional, she’s funny as f---," she added. "I guess my feeling sometimes is, Isn’t she giving us enough, guys?"

The 'Reputation' Look: A Nod to the Past, a Hint at the Future

Dunham's 'Reputation' era look not only pays homage to Swift's iconic album but also fuels speculation about a possible re-release. As Swift continues to re-record her earlier albums, fans are eagerly anticipating the return of the snake era. Dunham's appearance at the Eras Tour, with her 'trash' bodysuit and black hair, suggests that Swift's past is not forgotten, and perhaps even foreshadows a future filled with more surprises.
