Women's apparel retailer J Jill Group Inc has seen its fourth quarter net income fall by nearly half to $3.2 million, down from $6.2m in the same period a year ago.

The Massachusetts-based company reported a rise in sales for the quarter, however, to $114.9m from $107.9m a year earlier.

According to J Jill, extra costs were incurred during the quarter from a reworking of the company's merchandising focus away from its traditional catalogue model.
