We would recommend a cool hand wash and dry inside out. Do not bleach or mix colours when washing. Dry flat and in shade, iron on a cool setting.
When storing your knitwear we recommend the garment is folded as hanging can distort the knit over time. As cotton and cashmere are natural fibres pilling can appear over time but a gentle comb with a cashmere comb or de-bobbler should do it.
