Although accustomed to more creature comforts than those afforded at military posts, Mamie adjusted readily and joined her husband in moving 28 times before their retirement at the end of his term as president. During the Second World War, while promotion and fame came to "Ike", his wife lived in Washington, D.C. After he became president of Columbia University in 1948, the Eisenhowers purchased a farm (now the Eisenhower National Historic Site) at Gettysburg, Pennsylvania. It was the first home they had ever owned. His duties as commander of North Atlantic Treaty Organization forces—and hers as his hostess at a villa near Paris—delayed work on their dream home, finally completed in 1955. The Eisenhowers celebrated with a housewarming picnic for the staff at what would be their last temporary quarters: the White House. Diplomacy—and air travel—in the postwar world brought changes in their official hospitality. The Eisenhowers entertained an unprecedented number of heads of state and leaders of foreign governments. As First Lady, she was noted for her outgoing manner, her love of pretty clothes, some of them designed by Scaasi, jewelry, and her obvious pride in husband and home. Eisenhower was named one of the twelve best-dressed women in the country by the New York Dress Institute every year that she was First Lady. The "Mamie Look" involved a full-skirted dress, charm bracelets, pearls, little hats, and bobbed, banged hair. It was a modified version of the Dior's postwar "New Look." Her style included both high-and low-end items. Designers strongly associated with Eisenhower include Mollie Parnis, Trifari, and Sally Victor. Eisenhower wore a Nettie Rosenstein gown to the 1953 inaugural balls. It was pink peau de soie gown embroidered with more than 2,000 rhinestones. It is one of the most popular in the Smithsonian National Museum of American History's collection of inaugural gowns. Eisenhower paired the gown with matching gloves, and jewelry by Trifari. She carried a beaded purse by Judith Leiber (then an employee of Nettie Rosenstein). Her shoes by Delman had her name printed on the left instep. Eisenhower's fondness for a specific shade of pink, often called "First Lady" or "Mamie" pink, kicked off a national trend for pink clothing, housewares, and bathrooms. As First Lady, she was a gracious hostess but carefully guarded her privacy.
