If Kate Middleton is trying to prove she's still like the rest of us, she's doing a pretty good job.

Just days after she was seen wearing a glittery tiara, the Duchess of Cambridge hit the red carpet at the screening of "Mandela: Long Walk to Freedom" in a $35.90 necklace from Zara.

This isn't the first time Middleton, 31, has eschewed pricey items in favor of less expensive ones.

In fact, once she went on a shopping spree at her local Topshop, and picked up $170 worth of reasonably priced duds.

"She was low-key and casual," a staffer said at the time. "She seemed so normal."
