Fashion development & production
Keystone develops fashion products with specialist manufacturing partners, with a particular focus on fully fashioned knitwear and circular-knit garments. We coordinate the product from first brief and material selection through sampling, production and delivery. Production routes in Turkey and China are selected according to the product, yarn, quality, quantity, target price and timing.

Our fashion focus
The right production route depends on how the garment is constructed. Keystone works with specialist partners for knitted-to-shape products and for garments cut and sewn from circular-knit fabrics, then keeps development, approvals and follow-up connected.
