Knitwear businesses make, supply or sell garments and accessories produced by knitting yarn into fabric. Their ranges may include jumpers, cardigans, sweaters, dresses, tops, scarves, hats, gloves and socks, in materials such as wool, cotton, cashmere, synthetic fibres or blends. Some businesses focus on finished clothing, while others offer knitted textiles, yarn or equipment for people who knit by hand. Services can include designing and producing knitwear, selling ready-made items through shops or online, and taking commissions for made-to-measure or bespoke garments. Depending on the business, customers may also find repairs, alterations, garment care advice, knitting patterns, classes or supplies such as needles and yarn. Products vary in fit, style, weight and construction, from lightweight everyday layers to thicker garments intended for colder weather.
