HAIL TO THE FIRST WIFE: Barneys New York has gotten swept up in election fever. On Tuesday afternoon, workers were hanging portraits of the wives of 43 American presidents, painted by the artist Laurie Munn. The eyes may be the window to the soul, but for Munn, the hairstyle captured the essence of first ladies from Martha Washington to Laura Bush. Jacqueline Kennedy’s trademark sun-streaked bob and soft features were treated with reverence, while Hillary Rodham Clinton’s shoulder-length hair with bangs reflects her style-challenged early days in the White House. For the window installation, Munn also painted first lady hopefuls Michelle Obama and Cindy McCain. In the portrait, Obama is smiling, while McCain is all hard angles and appears to be laughing shrilly. Could the depictions have been influenced by Barneys creative director Simon Doonan? When asked recently whom he was supporting, Doonan said, “Apart from being the right candidate, [Barack] Obama looks better in a suit, which can only be a good thing.”
