Hilary Duff Proved That a Cropped Sweatshirt Is All You Need to Make Summer’s Go-To Outfit Ready for Fall

It’s no secret that dresses and sneakers have become summer’s unofficial uniform, as proven by celebrities like Jennifer Garner, Reese Witherspoon, and Emily Ratajkowski. But Hilary Duff has a genius style hack that will have you wearing the combo into the next season, too.

Earlier this week, the How I Met Your Father star, 34, was photographed in Los Angeles wearing a navy blue satin midi dress with Reebok sneakers. Her trick? She simply added a gray cropped crewneck sweatshirt from Alo Yoga, making her outfit a little more casual and wearable as the weather cools down.
