Fab has been using WWD for its four years of existence, but can you believe the fashion publication has been around for 100 years? That's quite a fabulous feat! So to celebrate its huge milestone, WWD threw an elaborate party at Cipriani in NYC last night. As you can imagine, the who's who of fashion flocked to congratulate. Mary-Kate and Ashley Olsen, Christian Siriano, and Coco Rocha were just a few of the famous faces who showed up in style.
