NARCISO VISITS OPRAH: Oprah Winfrey can soon start a fashion club to rival her book club at the rate she’s going. Just two weeks after having Tory Burch on “The Oprah Winfrey Show,” she’s tapped Narciso Rodriguez as one of her special guests. The show, scheduled to air this Tuesday, coincides with the fifth anniversary of O, The Oprah Magazine, and the May cover features Winfrey in a Rodriguez dress. In the birthday-bash episode, Winfrey shows behind-the-scenes footage of the cover shoot, as well as the creation of Rodriguez’s one-of-a-kind dress from sketches to samples and fittings. Rodriguez will also be presenting looks from his spring collection on models in a conversation with Winfrey.
