Coco Rocha made a major entrance last week at a Project Runway screening in NYC, and not just because her post-baby body is bangin’. Rocha was wearing—no, she was rocking—a fire-engine red monochrome pant suit by Zac Posen, complete with a slightly boot-cut silhouette and all-business stiletto heels. At first, we were perplexed. Pant suits haven’t been in since Hillary Clinton was in the White House! But then it all made sense. The ‘90s are back in every other way, from scrunchies to Nike Air Max sneakers, but this is a decidedly grown-up take on the trend. If you dare to suit up, take a page from Rocha’s book and shop for a skinny cut with minimalist details. (Leave those shoulder pads and gold buttons in the last millennium, please.) Thanks for the inspo, Coco!
