Despite the fact that this girl was born in 1999, which us feel older than Prince Phillip, Shipka has got savvy street style totally nailed.

She was spotted shopping at Barneys New York in Beverly Hills in a cute floral print skater skirt, cropped black sweater and black tasseled ankle boots.

"I've always loved classic Old Hollywood style," Kiernan told Lucky magazine. "Grace Kelly, Audrey Hepburn. They're so elegant and glamorous. And being on Mad Men has definitely triggered something. I'm inspired just walking into the wardrobe room and seeing all the beautiful '60s clothing and dresses."

2. She's already a mega fashionista
Kiernan sites Oscar de la Renta as her favourite designer, saying: "You can never go wrong with Oscar de la Renta!" She's also a big fan of Kenzo and Zac Posen. She's a girl after our own heart.
