Designers from Kai Milla, Marc Bouwer, Reem Acra (who dressed Jill Biden for the big night) and Isabel Toledo, whom she wore to the Inauguration, all sketched potential options for the new First Lady, and the fashion world waited to see her choice with bated breath. Turns out that Michelle chose a one-shouldered silk chiffon Jason Wu number covered in organza flowers and Swarovski cyrstals — and no one was more surprised than the designer himself, who learned of Michelle’s choice with the rest of the world. “I was in awe when I saw her. I was emotional, I was amazed,” Wu tells PEOPLE. The N.Y.C.-based 26-year-old designer, who along with four friends sewed the countless number of flowers onto the dress by hand, says “I wanted the dress to reflect hope, fantasy, a dream [because] this is a pretty surreal moment we’re living in.” As for the color, Wu told Meredith Veira on the Today Show, “I wanted to design a gown that would highlight her best features.” To accent the feminine gown, Michelle chose diamonds from Loree Rodkin, who says “The First Lady is a symbol of hope, courage and great style. Words can not describe the emotions I feel that Michelle Obama has allowed me to be a part of this glorious moment.” From her line, Michelle chose 60-carat white gold and triple rose cut diamond drop earrings, a 10 carat center stone white gold and black rhodium rose cut diamond ring and white gold and diamond bangles, which will become part of the permanent collection of the Smithsonian Museum. Check out all of Michelle’s stylish choices from the historic weekend.
