SWEET DREAMS: Norma Kamali will be launching her first line of sleepwear on walmart.com on Oct. 1. The eight-piece capsule collection is an expansion of Kamali’s exclusive lifestyle line of ready-to-wear, accessories, swimwear, activewear and children’s wear for the world’s largest retailer, which was brokered by Cherokee Inc. in 2008. The average retail will be $10 for solid and printed sleepwear items, which will also be sold at Wal-Mart stores at a later date. Sizes will range from XS to XL. Details of silhouettes and fabrics were not available. The collection will be marketed on a new Wal-Mart media platform driven by viral ads and social commerce, said a spokeswoman for the Kamali company.
