I Dare You to Find a Better Deal Than Sienna Miller's £30 Dress

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 £30. 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 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 Mango and Zara are here to help you test-drive the trend ASAP. Scroll down to see how Miller styled her dress and shop similar styles.

Erin Fitzpatrick
Senior News Editor

Erin got her start as a Who What Wear intern over 12 years ago—back when the site only published a single story per day. (Who What Wear has since increased that number twentyfold.) She graduated magna cum laude from USC, which is how she ended up moving to Los Angeles from her hometown of San Diego. In college, she also interned at Refinery29, where she was promoted to editorial assistant and then assistant editor. After nearly three years at R29, she came back to WWW in 2016, where she currently holds the title of senior news editor (as well as the unofficial title of resident royal expert—in case you haven't noticed her numerous Meghan Markle and Kate Middleton stories). She spends her days trying to incorporate her idols, Anna Wintour and Roger Federer, into as many stories as possible. Outside of work, she loves tennis, classic rock, traveling, and smothering her dog with affection.
