Gap Inc's Old Navy division on Monday said it is expanding its new Women's Plus line to more locations in a move that will take it to more than 150 stores nationwide.

Targeted at women sized 16-26, the collection has been constructed with fabrics and details such as stretch and side panelling for comfort.

"Our plus-size shoppers want great-looking yet affordable fashion options and we're excited to meet their needs with this new line," said Jonathan Finn, director of Old Navy Public Relations.
