Fashion Month is a marathon, not a sprint—and no one knows that better than Sydney Carlson. From the snowy scenes of Sandy Liang in New York to copious champagne at the Saint Laurent afterparty in Paris, our favorite globe-trotting fashionista ate, drank and dressed up all around the world, delivering a masterclass in doing fashion month right. 

Ahead is Sydney's photo diary from fashion month, complete with a little escargot experimentation and a cameo from sister, Devon. Come for a behind-the-scenes look at some of the most coveted fashion week tickets in town, and stay for a cake that will blow your Sandy Liang ballet heels off.
