Kylie Jenner broke the no-selfie rule at the Met Gala on May 1.
Attendees of the Met Gala are given one rule: no social media. That includes posting to Instagram, Snapchat, Facebook Live, Periscope, Vine, and any other social media platform, according to Teen Vogue.
Kylie broke the rule when she snapped a group selfie in the bathroom and shared it on Instagram.

The "no social media" policy at the Met Gala has been in effect since 2015.

In 2016, more than 600 people attended the Met Gala. For 2017, Anna Wintour, Vogue editor-in-chief and chairwoman of the gala, scaled down the invites to keep the event more intimate and private, according to The Sydney Morning Herald. The theme for 2017 was Comme des Garcons's Rei Kawakubo. A ticket to the gala started at $30,000 per person and went as high as $50,000.
