Silk-knit jumpsuit with spaghetti straps crafted in a tussah silk blend.

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 raised on farms, and their harvesting, warping, and dyeing is more complicated, this type of silk becomes an exclusive and cruelty-free fabric.

The selection of yarns used in Cortana's knitwear is carried out meticulously, selecting natural fibers of the highest quality. The tailoring is done in small specialized workshops in the Italian region of Reggio Emilia, which maintain an artisanal approach.
