Children's apparel manufacturer OshKosh B'Gosh Inc has reported a drop in first quarter profits of 4.3 per cent citing poor weather conditions and a tough economy for the drop in customer traffic and sales. The company reported that its net income for the quarter had dropped to $4.5m, or 36 cents a share, from the $4.7m, or 37 cents a share, recorded in the same period last year.
