NetflixHey, Upper East Siders.
It looks like Serena van der Woodsen had a small styling slip-up during season six, episode four of Gossip Girl.
The costume confusion was first pointed out by TikTok user @skyehanamaikai. In the episode, titled "Portrait of a Lady Alexander," Blake Lively's character is seen dining at a restaurant with Dan Humphrey (played by Penn Badgley). At first, she is seen wearing a coral-colored dress with bare legs. But as the scene continues, the S star is spotted with a pair of dark sweatpants underneath her ensemble.
The clip from the 2012 episode immediately went viral and garnered more than one million likes.
"I am a huge Gossip Girl fan and have probably seen the show more than 15 times," one commenter wrote. "I can't believe I missed this."
"I still stan Serena even with her sweats," added another.
While the reason behind the added layer wasn't confirmed, some viewers posted theories on TikTok.
"LOL, I worked on set, it's because she ripped her dress," a follower wrote.
"From my experience, if it's cold, most actors put layers on between takes and sometimes leave them on if the shot is from the waist up," guessed another.
Fans will get to see even more Gossip Girl fashion in the future. In 2019, it was announced that a reboot is coming to HBO Max. While the series will include some familiar aspects, like having Kristen Bell narrate, it will also include lots of new twists. However, an official premiere date has yet to be announced.
Until then, XOXO.
