Whether you’re partial to a crisp, preppy oxford or a romantic silk blouse, a long-sleeve button-down shirt can instantly transition a sleeveless dress from fall to winter. I’ve been wearing this Frame blouse underneath our fall tweed dresses, like Katherine shown here, and Tinsley (both now 40% off). Especially when paired with black tights and boots, plus a winter white coat to play up the contrast, this look always feels perfectly polished for a big day in the office.
