Sienna Miller's Airport Shoes Are Comfortable and Amazing

If there's one shoe style every It girl is wearing this fall, it's the Gucci Princetown slippers. And we totally get it—they're easy, unexpected with the furry lining, and effortlessly chic. Sienna Miller couldn't agree more.

While at Fiumicino Airport in Rome this week, she stepped out in the must-have shoe (so easy to get through security!) paired with a Rag & Bone coat, white tee, and skinny jeans.
