Fashion development & production

Knit expertise. Product thinking.

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

Two knit disciplines. One managed process.

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.

Sweaters, cardigans, dresses, skirts and knitted accessories developed through yarn, gauge and stitch.

02 · Circular knits

Knitted accessories

Beyond garments. A complete knit offer.

Accessories are an important part of our knitwear production. We develop and manufacture beanies, gloves and mittens, balaclavas and scarves as coordinated parts of a collection or as independent private-label programmes. Yarns, gauges, colours, dimensions and branding are adapted to each brief.
