Everyone's wearing flats lately, and we have Katie Holmes to thank. Holmes sported Mary Jane flats for years, and although she owns many pairs, she clearly has a favorite. Holmes brought out this strappy Mary Jane style again last week; it was trendy in 2023, but it's even trendier now. Strutting around New York City, Holmes donned $1,220 Miu Miu Mary Janes, a shoe that first debuted on the 2016 runway. Thankfully, we found a chic alternative on Nordstrom for just $130 - and it has the same classy yet retro flair.
