Kate Middleton Wears British Brands Reiss and Whistles for Official Engagement Photos Taken by Mario Testino

>> Kate Middleton and Prince William's official engagement photos, which Mario Testino took last month at St. James's Palace (the British monarchy's official headquarters), were released over the weekend. “I’m very happy that I’ve been asked to cover this historic moment, that the whole world was waiting for,” Testino said in a statement. “They are in their prime and brimming with happiness. I have never felt so much joy as when I see them together.”

Middleton's £385 ($611) Issa dress, which she wore to the engagement announcement, sold out within 24 hours; in the engagement photos, she wears a white dress from British brand Reiss, which is from the brand's Fall collection last season and no longer available (it is thought to have retailed for £159, or approximately $250), and a white blouse from British brand Whistles, which was still available yesterday for £95 (approx. $150).
