There are tons of summer trends you can try this season, but not all of them are attainable for less than $50. Sienna Miller's newest outfit, however, definitely is. She stepped out in New York City wearing H&M's Dress With Smocking, which rings in at an affordable $40. How can you beat that? But word to the wise: The dress is already selling out in multiple sizes.
The midi length is super practical for running around the city, while the cute smocking detail makes it look more expensive than it really is. Plus, blue gingham dresses are a timeless trend that you can rely on for infinite summers to come—and brands like Madewell, HVN, and Zara are here to help you test-drive the trend ASAP.
