If there’s one thing French and Spanish women have mastered, it’s effortless style with a hint of unexpected cool. This year, they’ve spoken—well, dressed—and confirmed the sneaker outfit that will reign supreme: slip dresses and sneakers. While the combination isn’t groundbreaking, the way they’re wearing it in 2025 feels fresh, modern, and undeniably chic. Think minimalist silk dresses paired with retro trainers, sporty socks peeking out just so, and a balance of polished and undone that European trendsetters always seem to perfect.

What makes this look so appealing is how effortlessly it transitions from day to night. Picture this: You’re strolling through the day in a slinky slip and fresh white sneakers for a casual brunch, and then head off to dinner in the same pretty look. Or you’re on vacation, where the slip-dress–and-sneaker combo works just as well for a rooftop aperitivo as it does for a day of exploring. It’s that rare outfit that hits the sweet spot between looking put-together and feeling completely relaxed—exactly what we want from summer dressing.

If you haven’t yet invested in a slip dress and the right sneakers, consider this your sign. Go for a midi-length slip in a neutral shade for maximum wearability, or opt for something bolder, like a bright hue or a subtle print, to channel the playful energy of Spanish street style. As for sneakers, classics like Adidas Sambas, New Balance 530s, or even a pair of stylish dad sneakers will do the trick. However you style it, this is the easy, pretty outfit formula that will dominate warm-weather wardrobes in 2025.
