While President Barack Obama and former Massachusetts Governor Mitt Romney battled it out at the first presidential debate last night, there was a different match-up in the front row: the looks worn by wives First Lady Michelle Obama and Ann Romney. Obama re-wore the cobalt and geometric print “Lavender Dress” from Preen’s fall 2011 collection with a matching jacket—a look she first donned on her trip to the UK last year. "We were thrilled to see Michelle wearing our dress and jacket again," Preen's Justin Thornton and Thea Bregazzi told InStyle.com in an email. "We love how she embraces color and style -- so refreshing and so effortless." Romney opted for a sleek white two-piece suit, designed by New York couturier Alfred Fiandaca, and classic two-strand pearls. Which look did you like better?
