Gwen Stefani’s return to New York Fashion Week came with a new licensing partner, Manhattan Trade Inc., and a more relaxed attitude. “It started with an African Eighties feel,” said Stefani, and the decidedly more casual looks worked to fun and funky effect. “In the past, the clothes were a little more theatrical,” she noted, “but this collection is all about being real.” There were the sculptural blazers for which L.A.M.B. is known, this time paired with draped skirts and balloon shorts. There was, in fact, a great deal of draping in the form of leopard print dresses, pleated diaper skirts and logo Ts, along with a hearty dose of denim — a Stefani favorite. It all had a great deal of charm.
