With the right care, cotton dresses can last for years. We would advise always checking the label to ensure no specific care instructions are required. As cotton lacks natural anti-bacterial and odor-resistant properties, it requires more frequent washing. 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. Once washed, gently stretch garments back into shape and always air dry flat away from direct heat. For dresses that are sure to see you through the rest of the season, shop the collection today.
