There are so many flat-shoe options on the market right now; it can be hard to pick between the countless pairs when shopping for your next style. But I’m here to tell you that the best option if you want your shoes to look expensive and polished with every outfit is to avoid classic colors like black and brown and instead opt for a navy blue pair. Don’t just take my word for it, though. Kendall Jenner is backing the flat-shoe color, too.

This week, when the supermodel went on a dinner date at Sushi Park in Los Angeles with Hailey Bieber, she chose a satin pair of flat mules from The Row, called the June Mules, which—you guessed it—were navy blue. She styled the flats with a matching knee-length skirt and a black boatneck T-shirt, adding a mustard-colored leather shoulder bag for a pop of color. Black or brown flats would have looked fine with the ensemble, but her choice to wear navy made the outfit appear infinitely more elegant and expensive. No added effort required.
