Olivia Palermo bundled up in a salt-and-pepper mockneck sweater and leather-sleeved blazer by Alexander Wang while grabbing lunch in NYC. She completed her look via black skinny jeans, cat-eye shades, and a posh Hermes tote, then added a pop of flair via red cap-toe French Sole flats and matching nail polish. This isn't the first time we've spotted Olivia working these cool-weather essentials, but we love how she brings new life to each piece by pairing them with different prints and textures. Take a cue from this fashion maven and add a leather-sleeve blazer into your Fall mix. Work it with black denim, a knit sweater, and cap-toe flats for a day of errands, a pencil skirt and silky blouse for the office, then these burgundy Helmut Lang trousers ($370) and black pumps for a night out.
