IN THE SWIM: Summer is about to fold, but Solid & Striped founders Isaac Ross and Morgan Curtis are getting ready to launch women’s swimwear. Made from quick-dry fabrics developed in Lake Como factories, the bikinis and one-piece suits will first be sold online in February. Curtis, a Central Saint Martins grad, and Ross, whom she grew up with, were undergrads at Cornell together. Solid & Striped is not her only pursuit. She is developing a lingerie line and she works full-time in design for her mother Jill Stuart.
