Once a year, San Diego becomes the world’s most star-studded locale for one weekend only, as A-listers flock to San Diego Comic-Con to promote their latest superhero and supernatural projects in front of the biggest comic book fans in the world. And while the conference center may be best associated with over-the-top cosplay, there are plenty of bold fashion and beauty moments to talk about as well. Case in point: Millie Bobby Brown’s red eyeliner that she wore to debut the new Godzilla: King of Monsters trailer. Also feeling colorful this week: Camila Cabello, who rocked blue-tinged braids for the most recent stop on Taylor Swift’s world tour, and Kim Kardashian, who donned a peachy smoky eye. Here, a look at the best beauty Instagrams of the week.
