Two days after the Academy Awards, Alan D. Schwartz showed up on “Entertainment Tonight” surrounded by models wearing evening gowns similar to the stars’ designer frocks.

Schwartz, who owns A.B.S. Clothing Collection Inc., of Los Angeles, is selling what he calls “interpretations” of the actresses’ high-end dresses at stores like Bloomingdale’s, Saks Fifth Avenue and Nieman Marcus. The dresses will be showing up at high school proms across the nation. Copying “is the backbone of the fashion business,” he proclaimed. “No one has a lock on fashion.”
