Feb. 11 was unofficially Yeezy Day. An audience of reportedly 20,000 professionals and members of the public with more than a passing interest in Kanye West — musically or fashion-wise — were lured to Madison Square Garden to witness one of the most unusual fashion spectacles ever. It was a wild, weird, confusing experience, the Garden’s floor mobbed with a mock-up refugee camp of models and extras wearing Yeezy Season 3, while West and crew played his new album, “The Life Of Pablo,” at a bone-shaking decibel. The Kardashians and Jenners watched from the sidelines. “You all acting like this s–t is regular,” said West at one point. He was wrong. No one thought it was an average fashion show.
