Women's sportswear designer and manufacturer Donnkenny Inc on Wednesday posted a sharp fall in first quarter net profit to $55,000 compared to $359,000 in the year-ago period amid soft sales in a weak retail environment. The New York-based firm, whose major labels include Pierre Cardin, Harve Benard and Victoria Jones, said sales for the quarter ended March 31 fell to $18.9m from $24.4m in the year prior.
