Wash at 30°
...or less! Wash similar colours together and be mindful not to overload the machine. Your garments should be able to move freely.
Dry Naturally
As with most garments, don't let your cotton styles dry in direct sunlight. Dry naturally and avoid dry-cleaning, if possible.
Iron Gently
Drying your cotton styles flat will prevent creases but, if you need to, you can iron on a medium height or use a steamer.
