All of Blue Willi's core products are machine-washable and should be tumble-dried for best comfort. When washing, please follow the instructions given on the care labels of all Blue Willi's garments. As the clothes are used and washed they will gradually change their appearance and leave the signature of the owner's natural wear, thus allowing the clothes to age and enhance their beauty. All Blue Willi's clothes come pre-washed, tumble-dried and thus pre-shrunk. Blue Willis sweaters, Blue Willis cardigan sweater
