Made with a 100% Cotton, these knit shells feature a vertical rib knit textured finish, double stitch trim at the neckline and arm openings and four way stretch qualities. Blue Willi's apparel is made with natural materials and only the finest dyes including Indigo are used. As the clothes are washed they will gradually change their appearance and leave the signature of the owners natural wear, thus allowing the clothes to age and enhance their beauty. All Blue Willi's clothes come pre-washed/shrunk and should be tumble dried. Easy care machine washable.
