Roslein Spa. was a fashion production entity based in Florence, Italy, active during the 1960s and early 1970s. The company was based in Florence (Firenze), a major hub for the "Made in Italy" movement during the 1950s and 1960s, heavily associated with the rise of Italian fashion following the first shows at the Pitti Palace in 1952. It is listed alongside other Italian production entities (such as Rowels and Premio Paride) in the archives of the Bocconi University, specifically within records regarding the "Premio Paride" competition held in Cortina in February 1973, indicating their participation in the high-fashion scene of that era.
