Sienna Miller Wore the "Boring" Flats Trend That's Back From the Dead

Most of the Sienna Miller paparazzi photos these days are of the busy actress and mom out and about on the streets of New York. That's why she's a trusted source for flat-shoe trends, as she's often spotted wearing them. (If you've ever been to NYC, you get it.) And while out earlier this week, Miller wore a casual fall outfit that was tailor-made for weekend errands and the like, yet stylish to a T.
In this instance, Miller wore a puff-sleeve sweater with straight-leg jeans and a Gucci bag worn crossbody. On her feet, she wore a "boring" flat-shoe trend that you might have thought was over in recent seasons but that the fashion industry has been buzzing about and brands have been embracing as of late: ballet flats. Miller opted for the most fashion-forward iteration of the trend, which includes an elongated toe and soft leather material. The low-key flats are certainly on the classic end of the trend spectrum, so you can rest easy in knowing that they're probably not going to be passé again anytime soon.
