Nordic climates pose humidity and temperature challenges for clothing. Start with fabric selection suited to moisture management: natural fibers breathe well, while synthetics can be easier to care for and quick-drying. After wearing, air clothes in a well-ventilated area away from direct sunlight before storage. For sweaters and outerwear, gentle washing with mild detergent, cold water, and a thorough rinse is usually enough; air-dry flat to prevent stretching. Protect delicate items from moths or mildew by storing in breathable garment bags and keeping the closet dry and well-ventilated. Color bleed is a risk—wash new pieces separately the first few times and use color-catching sheets when appropriate. Store seasonal items out of the main living areas to reduce dust exposure and maintain privacy. In humid coastal areas or during damp winters, consider a dehumidifier in the storage space to prevent mold growth. Regularly inspect zippers, seams, and elastic bands for wear, and repair or replace worn items promptly to maintain a neat, authentic appearance.
