Fabrics & materials

Traditional dyeing process using the blue pigment derived from indigo plants, requiring an oxygen-reducing vat; the fabric turns blue as it oxidises after removal from the dye.

A supporting fabric layer applied to the wrong side of garment sections such as collars, cuffs and waistbands to add body, stability and shape retention.

A double-knit fabric structure with two sets of needles that produces identical, smooth faces on both sides, more stable and less curling than single jersey.

A zip whose teeth are concealed behind a folded tape, sewn with a special foot so only a thin seam-like line shows on the finished garment.
