Blake Lively turned the sidewalk into her personal runway, rocking a daring look for a New York City event. And no, Upper East Siders, this wasn't a Serena van der Woodsen flashback. The former Gossip Girl star, 38, stepped out wearing a see-through burgundy netted top that gave a peek at her décolletage and midriff, layered under a brown blazer featuring a statement brooch. She paired the garments with a high-waisted brown midi skirt on Friday, September 5. Lively completed her eye-catching ensemble with lace-up, blue suede knee-high boots that had matching burgundy buttons.
