Isaia Isaia's history and success are based on the concept of made in Naples, a value meant both as neapolitan tailoring tradition and as exclusive product knowledge, esteemed around the world. A value that is rooted in the company's DNA and in that of all the people who are a part of it, as some have been for generations. In fact, Isaia produces its garments only and exclusively in Italy, at Casalnuovo di Napoli, subjecting them to severe quality checks during the many step of production. The brand's success is due to its ability to reinterpret the concept of history and to combine tradition with innovation, the sartorial culture of needle and thread with cutting-edge technologies, while constantly innovating its style.
