It’s cute but also cooling.

  • Reese Witherspoon attended a speaker session at the Cannes Lions International Festival of Creativity 2025.
  • For the outing, she wore a white mini dress and coordinating ankle-strap heels. 
  • A white mini is a summer-perfect alternative to a LBD; it’s versatile, cute, and cooling in the heat.

It’s getting really toasty here in New York City and I’m going through the same beginning-of-summer crisis that happens every year: I don’t know what to wear! Specifically, I don’t know what to wear in this heat without setting foot outside and breaking a sweat in a millisecond. That is, until I saw Reese Witherspoon’s simple summer outfit that I predict I’ll be living in 24/7 until September. 

Witherspoon was photographed at the Cannes Lions International Festival of Creativity 2025, and for the outing, she went with a simple outfit that proves that sometimes, the most unfussy combo is the most impactful. She opted for an itty-bitty white dress with a semi-structured bodice, puffy cap sleeves, and seamed detailing throughout. She paired her dress with white ankle-strap pumps, rounding out the look with gold earrings and simple makeup.

Witherspoon’s LWD is a summer-perfect alternative to a LBD. We all know that wearing all-black in the heat is semi-chaotic, though alas, I’m guilty of doing that because, well, I live in New York City. Like a LBD, a LWD is easy to wear, incredibly versatile, and looks cute, whether you pair it with heels à la Witherspoon or sneakers for a long day of running around the city. But the best part? You’ll stay cool doing so, especially if you opt for a breezy, lightweight fabric, like this linen option from Madewell. 

Not to mention, white reflects the sun, which means wearing said color in the summertime is the most foolproof way to stay cool if you’re spending the day in the beating sun. Think of it like a wearable A/C—and given the upcoming NYC heat, I’m certainly snagging a white mini or two thanks to Witherspoon’s recommendation. Shop some styles I’m eyeing below—especially the Wilfred mini that’s subtly sexy.
