Crisp leaves, pumpkin everything, movie nights and sweaters - they all channel autumn. And ever since we discovered these 17 designer-looking sweaters, we've been counting down the days 'til the official first day of fall. With temperatures dropping and trees changing, it's time to bring 'em out! These cozy sweaters channel Nantucket and Hamptons vibes at the very same time, giving sophisticated, refined silhouettes a nautical twist. We pulled together oversized sweaters, wool-blend options and polo-style picks that feel rich.
