    Do I have to pay shipping costs?

    Absolutely not! We cover all shipping costs within the USA. Thank you for choosing Guilly.

    How long does delivery take?

    Once your order is processed, delivery typically takes 4–6 business days within the USA. You’ll receive a tracking link by email as soon as your package is on its way.

    Are they easy to wash?

    For the best care of your underwear, we recommend washing dark and light colors separately to prevent staining. Use cold or lukewarm water below 40°C to protect the fabric, maintain its quality, and ensure long lasting durability.
