After marrying French banker Olivier Sarkozy in November 2015, Mary-Kate Olsen continued to refine the quietly luxurious aesthetic that she and twin sister Ashley had turned into a modern-day uniform.
Just months after the wedding, the fashion mogul was spotted at LAX in April 2016—her look a study in minimalist sophistication and footwear precision.

The Power of Square-Toe Mules in Olsen Twin Fashion
Wearing tailored black trousers, an ivory coat, and square-toed leather mules, she demonstrated how the Olsen twins helped usher in a revival of structured, architectural shoe silhouettes that still influence designers today.
Though Mary-Kate and Olivier ultimately split in 2020, finalizing their divorce in January 2021, her understated airport style from that period remains a timeless example of The Row’s pared-back elegance and the enduring power of square-toe shoes.
Mary-Kate arrived at the Los Angeles International Airport with her husband, heading straight to the car while trying to avoid the cameras. The Full House actress wore a white shirt and black pants underneath a chic-looking full-length coat.
The celebrity-turned-entrepreneur shielded her eyes behind Oliver Peoples × The Row sunglasses and finished her minimalist ensemble with black square-toe mules and a structured tote. This pairing perfectly reflected the Olsen twins’ quiet-luxury aesthetic.

How the Square-Toe Trend Evolved from the Olsens to the Runway
Square-toe mules have remained popular for both aesthetic and practical reasons. Their bold, structured shape offers a modern edge that stands out from classic rounded or pointed toes, a look championed by designers like Bottega Veneta and embraced by The Row’s architectural minimalism.
The style also taps into early-2000s nostalgia while feeling fresh and relevant, blending comfort and sophistication through its open-back design and wider toe box. From luxury labels such as Wandler and Rejina Pyo to accessible brands like Zara and Mango, square-toe mules continue to dominate both runway and street style — proof that Mary-Kate’s effortless 2016 look helped set the tone for a trend that’s still thriving today.
