And in our experience, the only way to beat the late-September blues is with a fierce new outerwear wardrobe. Enter the sharply tailored double-breasted blazers we've spotted on a coterie of street style stars (Helena Bordon, Leandra Medine, Kate Davidson Hudson, et al). From the waist-cinching silhouette to the hint of shoulder pads, the look is so '80s redux-cool, we don't mind that it's only suitable for cooler temps. 

And now for some good news: we're happy to report you can rock the style both day and night. As Sarah Jessica Parker proves below, a navy, brass-buttoned blazer gives a chic edge to your usual jeans-and-sneaks ensemble.
