  • What is your underwear made from?
    We carefully select fabrics for our underwear that are known for their softness, functionality, and sustainable qualities. Among the fabrics we use are Organic Cotton, Tencel, and upcycled deadstock materials. These materials not only provide a comfortable wearing experience but also align with our commitment to promoting sustainability and minimising environmental impact.
  • Where is your underwear made?
    We take great pride in manufacturing our underwear in London and our basics in Wales. By choosing to produce locally, we can establish close working relationships with our manufacturers. We are dedicated to maintaining ethical working conditions and ensuring fair wages for all involved. This approach allows us to have full control over the production process and uphold our commitment to ethical and responsible practices.
  • What packaging do you use?
    We ship everything in compostable packaging from
  • How do I care for my Sundies product?
    For optimal care of your Sundies, we recommend washing your underwear or basics on a gentle cycle, preferably with similar colors or separately. When they are still damp, gently reshape them to maintain their form. Whenever possible, air drying naturally is beneficial, but if you choose to use a dryer, we suggest using a low heat setting. By following these care instructions, you can ensure that your Sundies last longer.
  • Where do you ship to?
    We ship Internationally, but some orders may incur a customs charge.
  • I have been asked to pay a duty fee to receive my delivery - what is this for?
    Several countries apply a duty or tax on packages imported from the UK that exceed a certain value. In the event that your order from Sundies surpasses this limit, there may be a duty fee associated with receiving your package. We kindly recommend checking your country's tax specifications before placing your order, as Sundies cannot assume responsibility for any tax payments.
  • How long will my parcel take to arrive?
    We strive to dispatch orders within 3-5 working days, but often we are able to do so within 2 days. Please keep in mind that we operate as a small team consisting of just two members. We kindly ask for your patience and understanding during busier periods.
