Once you’ve invested in a cotton item, preserving the fabric is a must. Cotton is a durable and sturdy fabric, but does need special attention to keep it looking its best. We suggest checking the care instructions for the specific item before washing. Cotton is durable, soft and comfortable, but it does need to be cared for properly to ensure it doesn’t shrink. Whether it is made from pure cotton or a cotton-blend, any garments that contain cotton are prone to shrinkage when exposed to heat. To prevent items from shrinking, always follow the instructions on the care label carefully and machine wash at a temperature of 30°C or below. Allow to air dry naturally. As some cotton fabrics can crease easily, it is best to iron when slightly damp or use an iron with steam. Discover our wide selection of 13Month sweats. Shop new season and sale now.
