In the world of fashion, trends often come back like old loves that we can't forget. But this time we're not talking about the classic white sneakers that we've worn until they're almost worn out over the past decade. The ballerina flats, which you might associate with Audrey Hepburn or Paris in the early 2000s, are confidently taking center stage. Although this iconic footwear has long been sidelined and relegated to the background as a symbol of conservative elegance, this spring the ballerina flats are making a comeback, completely revamped, bolder and more interesting than ever before.
