Kylie Jenner stole the spotlight and stirred outrage at Jeff Bezos and Lauren Sánchez’s star-studded Venice wedding by wearing a white, figure-hugging gown. Netizens slammed her for breaking the ultimate guest rule: never wear white to someone else’s big day. The “mystery dress,” called icy blue by designers, looked bridal to many online. As A-listers like Oprah, Tom Brady, and Ivanka Trump watched on, Kylie’s look became the most controversial moment of the $50 million bash.
