Outside, it was dreary and gloomy, a fitting atmosphere to remember 9/11, but inside the Bryant Park tents, Carmen Marc Valvo whisked us away to a world of Springtime glamour. Beloved for his red-carpet gowns, the designer’s collection this morning also featured shorter cocktail dresses a bit of daywear, and some swimsuits that would make any woman feel like a celebrity. As the final pieces of collection went down the runway, the ethereal soundtrack (music by Michel Gaubert) reminded me that the clothes felt fluid and ethereal, too. Sea shells, with their seductive spiral structure and soft, iridescent hues, were the designer’s inspiration. And, like nature’s creations, those of Carmen Marc Valvo were naturally beautiful.
