FAQ
How do I know what size to buy?
See above our size guide.
How do I care for my underwear?
- Washing: Machine wash your underwear in cold water with similar colours. This helps prevent colour bleeding and keeps the prints vibrant.
- Avoid Bleach: Do not use bleach or harsh detergents, as they can damage the fibres and colours of the underwear.
- Drying: For best results, line dry your underwear. If you prefer machine drying, use a low heat setting. High heat can cause shrinkage and affect the stretch of the waistband.
Can I return my underwear?
For hygiene reasons, underwear can't be returned. Please check our size guide before ordering to find the right fit.
