Department store retailer Kohl's Corporation is extending its partnership with designer Vera Wang into the junior's category, with a new line that will launch in its stores next August.

The Princess Vera Wang collection will be licensed to Kohl's under a long-term agreement by a subsidiary of Vera Wang Group. The retailer will be the exclusive merchandise provider and marketer in the US.

For Kohl's, which operates 1,127 stores, the move is part of efforts to build on the strength of its exclusive and private brand ranges, which accounted for 52% of sales in the third quarter of 2011, up significantly from 2010.

"When we first partnered with Vera Wang in 2007 to launch Simply Vera Vera Wang, there was immediate acceptance and strong response from our contemporary customer," said Kevin Mansell, Kohl's chairman, president and CEO.

"We are confident bringing this level of fashion and quality to our junior's business allows us to increase the value proposition to our younger shoppers and delivers on our commitment to offer world-class brands in each category."

The new juniors' line will bemanaged out of Kohl's New York design office.

Since its launch, Simply Vera Vera Wang has been the leading exclusive brand in the women's contemporary category, Kohl's said, and has experienced continued growth. From spring 2012 it is also expanding into cosmetics and bridal jewellery.
