Top with wide straps and tailored in non-cruelty tussah silk knit. Tussah silk or shantung is a type of wild silk produced by silkworms of the same name that feed on oak and juniper leaves. Because they cannot be farmed and their collection, warping, and dyeing is more complicated, this type of silk becomes an exclusive and cruelty-free fabric. The selection of threads used in Cortana knitwear is done meticulously, choosing natural fibers of the highest quality. The garments are made in small specialized workshops in the Italian region of Reggio Emilia, maintaining a craftsmanship approach.
