Maybe you've never heard of Roberto Capucci, but you know his work.
That's because the silhouette of one of his grandest legacies - the Bocciolo - has been echoed in the later work of designers you know well: Valentino, Yves St. Laurent, and Oscar de la Renta.
He debuted that piece, known better as the Bud Dress, in Florence in 1956.
The cocktail-length dress with its super-cinched waist blooms into a voluminous layered skirt resembling rose petals - and it's one of 83 pieces composing the Philadelphia Museum of Art's costume exhibition "Roberto Capucci: Art Into Fashion," which opens Wednesday.
"Capucci was doing this kind of sculptural work in the 1950s before everybody," said Clara Henry, director of the fashion design program at Philadelphia University. "I look at his pieces and I'm in awe, simply in awe. He's not known to the mass market, but he has been such an inspirational source."
