The designer is a huge fan of the future British queen and believes she shares the same eye for effortless fashion and impeccable taste as the US first lady.
He told vogue.com: "When Barack Obama first became well known and everyone started looking at Mrs Obama I thought to myself 'This is a very different, modern-looking couple.' When I designed the outfit for the Michelle's first official portrait no one thought she would wear matte jersey but she did. Past women in the same position had always worn a tailored suit. When I look at Kate I see a changing of the guard in what is considered elegant. She is likes to look easy but chic. I would liken her to Obama and Carla Bruni in that way. All these women are in situations where they shaking off the formal suits of their predecessors."
Although he has not been asked to design her wedding dress, Michael has an idea of what he thinks Kate should wear when she marries Prince William next April.
He said: "If I was asked I would take the dress out of the realm of a traditional princess bride. A fabulous matte jersey combined with beautiful embroidery would be nice. The best clothes are a frame for the woman wearing it. It would be cut very well in just the perfect fabric."
