While sitting front row during London Fashion Week, Olivia Palermo proved her ongoing affinity for Tibi — twofold. The style pro worked her Tibi mesh sweater ($175, originally $250) into two standout looks! It's just further proof that this fashion star knows how to rework her closet — or in this case, the contents of her suitcase. At the Temperley London show (left), she mixed the prints in her knit with a zigzag miniskirt, then finished with a black-and-white Tibi blazer and red printed pumps for a funky take on the ladylike look. Prior to that, Olivia sported her Tibi sweater at Sass & Bide (right) with a more laid-back twist, donning a double-zip cape, Paige Premium skinny jeans ($199), and the same graphic heels for a sexy but casual approach. Now it's your turn — score Olivia's exact Tibi sweater at 30 percent off to channel some Palermo-inspired style for work, weekend, and beyond.
