Miranda Kerr nude pics in Harper's Bazaar: We think she's selling boots

If the shoe fits, wear it -- and only that. At least that's how Miranda Kerr seems to be interpreting the saying in the September issue of Harper's Bazaar.

The model poses in a pair of thigh-high Hermes boots and nothing else for her spread in the magazine.

"I really love over-the-knee boots. I think they're super sexy and they're fun," she says in a behind-the-scenes video from the photo shoot. "And they're also very strong and empowering."

The mom to 19-month-old Flynn and wife to Orlando Bloom also shares her style secrets with the mag.

"For me it's all about keeping things simple and feeling comfortable in what I am wearing," Kerr says. "I prefer investing in classic, well-tailored pieces."
