Olivia Palermo brightened up the New Yorkers for Children Spring Dinner Dance in this sunny design—“I feel like Big Bird!” she told—and also brightened the day of its designer, Katie Ermilio. “She’s one of the younger designers I really want to support,” Palermo said of why she chose the look, a silk cap-sleeve piece with a jewel neckline and tulle-lined skirt, which she accessorized with a jeweled Zara belt and a clutch and shoes by Jimmy Choo. And Ermilio appreciates the style star’s encouragement: “I love Olivia's ability to make a style completely her own,” the designer said. (Fun fact: Ermilio is the granddaughter of Grace Kelly’s personal clothier.) “She's always making me see my clothes in new ways which is amazing.” This look also affirms women should be unafraid of yellow: “It's one of the best colors for spring! Mix up a little yellow dress with a jeweled belt—it makes for a perfect spring date night outfit.” A version of the dress with a shorter skirt is available exclusively at Barneys New York ($2,750 at
