On November 2, 2015, Lady Gaga emerged from a New York City building wearing a black and white abstract print jumpsuit, which she paired with a matching leather-trimmed coat, and accessorized with a turban and monocle. This one outfit threw down the gauntlet for every other celebrity with advanced degrees in fashion to compete with one another for craziest one-piece ensemble of the week. Kendall and Kylie Jenner quickly accepted the challenge, each sister showing up to Kendall’s 20th birthday party in knockout numbers with their own eccentric twists. January Jones finished the competition out really strong by wearing a ballerina dress with a Big Bird hemline and sheer pants. There were a few in between, too — Saoirse Ronan, Katy Perry, and more — and all were winners. Mark this week in the history books as the seven days that changed the jumpsuit forever.
