Keeping Your Tee Looking Fresh
Cotton is easy to love and easy to care for. A few simple habits will keep the print sharp and the fabric soft for years:- Wash: Machine wash cold (30°C or below) with similar colors. Turn inside out to protect the print.
- Detergent: Stick to a mild, bleach-free formula to preserve color vibrancy and fabric softness.
- Dry: Tumble dry low or hang dry — this minimizes shrinkage and helps the print last longer.
- Iron: Iron inside out on medium heat only if needed. Never press directly on the design.
- Avoid: Bleach, dry cleaning, and high heat, which can fade, crack, or shrink the fabric.
- Storage: Fold and store in a cool, dry spot to keep it wrinkle-free and ready to wear.
