IRVINE, Calif. — Designer Kelly Gray wants to give her St. John customers black-tie options that go beyond big dramatic gowns. And that’s precisely what she did in her fall show. She served up lots of whispery chiffon evening pants in a mostly black, white or cream palette, and paired them with sophisticated tops with subtle details — draped necks, fitted waists or touches of sparkle. Here, her off-the-shoulder wool and rayon top and silk palazzo pants. For more on the St. John collection, see page 4.
