Why Are No Pictures Allowed?
In 2015, Anna Wintour enforced a "no social media" rule, which Kendall Jenner famously violated with a bathroom selfie. But she's not the only one — plenty of stars have posted snaps. The idea is to make the evening seem impossibly exclusive, and a treat for only those who are invited to the party. Plus, once the exhibit is open to the public, anyone can check out the gorgeous displays in person, which is highly encouraged.
