Addison Rae took a page out of BFF Kourtney Kardashian's style playbook with her debut Met Gala look

• "He's All That" star Addison Rae was one of seven influencers who attended the Met Gala on Monday.
• For her debut, Rae appeared on the red carpet in a crimson red dress and blonde lob.
• Fans drew similarities between her dress and one her BFF Kourtney Kardashian wore in 2019.

Addison Rae Easterling, best known as Addison Rae, made her Met Gala debut as one of the seven social-media influencers to be given a coveted invite to fashion's biggest night.

In the hours leading up to her rumored appearance on the red carpet on Monday, the 20-year-old TikTok star hinted at the inspiration behind her outfit through her Instagram stories, according to People Magazine.

After posting a series of photos of Marilyn Monroe, Cindy Crawford, Cameron Diaz, Britney Spears, and Kate Moss all dressed in red, People reports, Rae paired her new platinum-blonde lob with a crimson red vintage 2003 Tom Ford for Gucci gown for the event.

People added that during her Vogue red carpet interview, Rae said she and her image architect Law Roach wanted to choose an American designer who empowers women.

"I wanted to pay homage to that," she said, according to People. "We found exactly what kind of message we wanted to put across and this dress was perfect for that."

Outside of the outfit inspiration she shared with her nearly 40 million Instagram followers, another influence for her Met Gala look may have been her BFF Kourtney Kardashian, who previously shared Instagram photos of herself wearing a very similar dress to the annual Kardashian family Christmas party in 2019, according to Cosmopolitan.

While there are key differences between the two corseted dresses, namely the existence of straps on Rae's, some fans on Twitter were quick to speculate that the dresses were actually the same and that the TikTok star may have even borrowed the dress from Kardashian's wardrobe.

However, in an email to Insider, a representative for Rae confirmed that the dresses were not the same.

Meanwhile, Kardashian, who was at the MTV Video Music Awards in New York City alongside her boyfriend Travis Barker on Sunday, did not make an appearance at the 2021 Met Gala, themed "In America: A Lexicon of Fashion."

Her sisters Kim Kardashian West and Kendall Jenner did, however, as did their mother Kris Jenner, who was accompanied by boyfriend Corey Gamble.
