Milanese clothing company founded in 1971 by Maria Angela Corbetta. The name is an acronym of Società Esercizi Magazzini. Corbetta produces low-cost clothes in a factory/workshop in Luzzano in Bergamo and sells them through 15 own-brand shops in the leading cities of north and central Italy. She produces a hundred or so examples of every model, taking care to keep things simple and rigorous, partly to keep production costs down. In 1997, she produced Sunmoon, an underwear collection. Her Milanese customers have renamed the shop in Corso Vittorio Emanuele “Sem Laurent.”
