Duchess Kate buys American!

For her second outfit on Friday night in Los Angeles alongside Prince William, her Royal Highness, 29, opted for an American designer to attend a reception at the consular general's residence.

In a number that's sure to sell out quickly, Kate showed off her slim physique in a "Maja" green silk dress by Diane von Furstenberg. She pared the vibrant frock with a leopard purse by DVF as well. See more shots of Kate's stunning DVF dress.

It was a radical costume change for the British beauty's first night in the U.S., who touched down in the Sunshine State and attended a tech conference in Beverly Hills in a super-pale lavender Peridot dress by Roksanda Illinic.
