Billie Eilish in a Large Blue Shirt” refers to a series of online jokes featuring the American recording artist Billie Eilish wearing an oversized, blue button-down shirt. 

This meme gained traction after Billie Eilish shared a photo on Instagram on November 12th, 2018, where she was seen in the mentioned outfit alongside fellow artists Tierra Whack and SZA. Online users humorously compared her attire to Soulja Boy and Big Smoke.

Eilish’s Instagram post garnered over 2 million likes within a year. The image was also shared on her Facebook page, amassing more than 25,000 reactions, 1,000 comments, and 3,700 shares in under a year. Fans responded with playful mockery, creating exaggerated versions of the image.

In December 2018, Twitter users juxtaposed Billie Eilish’s photo with an image of Soulja Boy, humorously suggesting that “Soulja Boy walked so Billie Eilish could run.” The meme continued to evolve, and by April 2019, it was incorporated into the “Nobody” meme format by a Twitter user @roman_nfkrz, gaining over 9,300 retweets and 63,000 likes in less than a month.
