With all the speculation around Barack Obama’s Vice Presidential pick, we almost lost sight of another important choice — what is his ultra-stylish wife wearing for her speech at the Democratic National Convention? Michelle Obama is relying on Chicago-based Maria Pinto for a turquoise blue ’50s-inspired style in double-faced wool for her prime-time address tonight. Michelle famously paired a sharp purple sheath from the designer with an Azzedine Alaia belt for her husband’s primary kickoff. Katie McCormick Lelyveld, Michelle Obama’s communications director, confirms the choice for the dress to PEOPLE, adding that there was very little doubt as to the choice. “She’s a friend and hometown favorite.” But as any woman knows, there can always be a last minute switch. Tune into the convention coverage tonight to see her final wardrobe choice — and of course, to hear her speech.
