We're big fans of the fashion sweatshirt over here at Refinery29. Printed or embellished, fitted or oversized, we love the way these cozy little numbers look fashion-forward but feel like pajamas. And, the coolest ones, in our minds, are always vintage. These one-of-a-kind cover-ups are your best bet for adding that downtown element to your summer wardrobe. Wear it with sophisticated shorts (we like prints or pairs in interesting textures) and a bright lip.
