Since their post-aughts resurgence, ballet flats have been trending up over the past few years. And I must admit, I'm not surprised—there are so many different designs and colors out there, and every few months, one fresh version of the shoe rises to the top. Right now we're in the midst of a silver flats wave beloved by NYC fashionistas, but I predict that Margot Robbie just debuted a new ballet flat trend that's just as—if not more—exciting. Brace yourself (and your closet) for ballet flat mules, a cool-yet-elegant style that even Barbie herself can't resist.
Robbie was spotted wearing a super fancy Manolo Blahnik pair ($745) while out and about in New York City just last weekend. And the way she styled them to perfection with an oversized denim buttom-up and matching wide-leg jeans? I still can't get over how good the ensemble looked, but, of course, I was especially drawn to those hybrid slip-ons.
