Olsen Coded and Time Tested: The Flat-Shoe Style It Girls in NYC Are Wearing With Jeans and a Tee
Whether you're in your 40s, like the Olsens and Olivia Munn, or in your 20s, shop the ageless and chic flats.
At least once a year, the same debate resurfaces in fashion: Are Birkenstock sandals "in" or "out"? But for those who truly understand effortless style, the answer remains a hard yes. It's time we collectively acknowledge that these iconic sandals, known as the Arizona and worn by the likes of Ashley Olsen, Kendall Jenner, Kaia Gerber, and Gigi Hadid, aren't a fleeting trend but a time-tested classic that deserves a permanent spot in any wardrobe. That said, how you style them matters. In 2026, breathing new life into these flats comes down to pairing them with elevated basics, as Olivia Munn recently demonstrated.
While stepping out in New York City this week, Munn served up a master class in relaxed, off-duty dressing. She was spotted wearing Birkenstock Arizona sandals styled in an Olsen-coded fashion—with socks. To balance the casual footwear, she paired them with straight-leg denim and a crisp white T-shirt.
