We reported Beyonce's newest endeavor, campaigning for Emporio Armani's 'Diamonds' fragrance, with the launch of her feisty 'Diamonds Are A Girls Best Friend' TV spot, this week. She hosted the launch of the release, on the floor of NYC Macy's. She was quite classy - perfect hair (extensions?), a gorgeous Armani knee-length dress in teal, strappy peep toe heels (Jimmy Choo?). But what was up with the stockings? I sort of get the look if she's trying to go for a very conservative classy, but the knee-length of the dress was already plenty conservative. Thoughts? (Oh, but I have no ill word to say against the new print ad launched this week! Picture perfect, B!)
