Destination Maternity Corp has signed an exclusive supply deal with US retailer Macy's for its e-commerce business.

The US maternity retailer has expanded its apparel leased department relationship with Macy's, becoming the exclusive provider of maternity and nursing apparel for macys.com. The deal will be effective from late January 2014.

Destination Maternity has had a supply deal with Macy's stores for around 20 years. It currently operates leased departments in over 600 Macy's locations.

"We are pleased to continue to build upon our exclusive and longstanding relationship with Macy's, which has been a successful partnership for both companies and a win for our customers," said Destination Maternity CEO Ed Krell. "The ability to reach Macy's customers via the additional channel of macys.com will enable us to cater to even more moms-to-be, on an omnichannel basis, and provide them with immediate access at any time to a compelling and unparalleled assortment of maternity and nursing wear."
