Sales at plus-size women's clothing retailer Charming Shoppes Inc fell 4 per cent on a consolidated basis last month, hurt by 11 per cent lower sales at its Fashion Bug chain. Charming Shoppes said total sales for the four weeks ended 2 February increased 65 per cent to $133.7 million, from $81 million a year earlier, due to the addition of the Lane Bryant chain, which it acquired last August.
