Lena Dunham Makes Rare Appearance at Taylor Swift's Eras Tour in “Reputation”-Coded Look Featuring Jet-Black Hair

"Didn't even get more pics because I was dancing til I sweat through this bodysuit," the 'Girls' creator shared on Instagram

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.

The star also showed off her newly black hair, which she first revealed via Instagram in June.

In the following slide in Dunham's story, she shared a video of herself and fellow VIP concert guests dancing along to Swift's hit "Cruel Summer."

"Okay I lied, one video," she captioned the post.

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 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?"
