Leading apparel manufacturer Kellwood Co on Friday posted a hefty 65 per cent plunge in first quarter net profit compared to the year-ago period amid a sharp fall in sales. The St Louis-based firm said poor sales, particularly of its women's sportswear, was behind the steep fall in net income to $8.6 million from $25.1m in 2001. The figures include an $8.9m provision for business and facilities realignment.
