The Princess Beatrice Royal Wedding Hat meme stems from the 2011 wedding of Prince William and Catherine Middleton. Beatrice arrived wearing an avant-garde fascinator designed by Philip Treacy, which immediately went viral for its unique, sculptural shape. Netizens quickly compared the accessory to a toilet seat, a pretzel, a Fallopian tube, and even a portal to another dimension. The hat became such a cultural phenomenon that it spawned its own Facebook page and was eventually auctioned on eBay for charity, raising over £80,000. Today, it remains a quintessential example of 'internet vs. royal protocol,' used to highlight bizarre fashion choices or moments of unintentional comedy.
