Wendy Williams had advice for women investing in a first pair of Christian Louboutins at the designer’s 20th anniversary bash Tuesday at Bergdorf Goodman. “Don’t get fancy and outrageous,” she said. “Stay practical. Black or nude.” Williams recalled waiting “three months” to get her first pair, but the sizing was wrong and one shoe “fit like a flip-flop.” “I was so sad, but I wouldn’t return them,” she added. Guests included Beth Shak, Linda Fargo and Tinsley Mortimer.
