In-the-know fashion girls and industry insiders always turn to Moda Operandi when they're seeking a special piece you oftentimes won't find anywhere else. The Lauren Santo Domingo–founded site and its exclusive online trunk shows are the golden ticket to acquiring straight-off-the-runway pieces and upcoming collections before they sell out. The rest of the inventory is an expertly curated assortment of high-end pieces you might've recently spotted on street style stars and celebrities. But before you get discouraged by the term "high end," we're happy to report the site is currently running a weeklong (ending this Sunday) 50% off friends and family sale (enter code FRIENDS at checkout), with a large assortment of its winter collections included in the selection. And because a really good friends and family sale can be quite overwhelming, we did our due diligence and combed through every single piece. Shop our picks below!
