Who's Katharine McPhee? She's a TV actress. And she's got a lovely bottom. In fact, they all have lovely bottoms. It's the way Naomi makes them work it. Walking isn't as easy as it looks, you know. 

Main instructions include "Stand in the middle", "WAIT FOR HER, WAIT FOR HER!" and "YOU CAN USE HIM AS A PROP." Now, go and make your millions!!

If anyone can enlighten us regarding the designer of Naomi's sandals and Katharine's dress, we'd be most grateful.
