You Have To See Sienna's Adorable Jumpsuit

Rompers were all the rage this summer. It was nearly impossible to visit a fashion blog, scroll your Instagram feed, or even flip through a magazine without seeing some version of the stylish onesie. But now it's winter, it's cold, we gotta cover up. But don't worry, there's an alternative. Sienna Miller wore a floral Reformation Felice jumpsuit to a Rolls Royce exhibit at the Saatchi Gallery in London and provided us with a practical way to wear the favorite summer trend when the temperatures drop.

The British actress's flowing white jumpsuit with wide leg pants and black floral motifs was not only season-appropriate (and totally adorable), but it also would be a perfect holiday party look for those who don't want to wear a dress, but need to be a little more formal than basic pants allow for. And depending how you choose accessories (I NEED her red leather pumps), it could be dressed up or down to transition the look from day to night. It isn't overtly feminine, but yet doesn't quite venture into menswear, so it really is the perfect medium. Flawless, Sienna, once again. And P.S. props for matching your red lipstick perfectly to your shoes.
