Leading retailer of large-size women's fashions, Charming Shoppes Inc, said on Monday its first quarter net profit almost doubled from the year-ago period as higher spring merchandise sales at its Lane Bryant unit cancelled out rising business costs. The Pennsylvania-based company, which runs the Fashion Bug and Lane Bryant chains, said in a statement its net income surged to $16.3 million, or 14 cents a share, from $8.4m, or eight cents a share, in the year prior quarter.
