Returns and Exchanges

We are happy to offer a refund or exchange for items returned to us unworn with tags attached, within 90 days of delivery. Any items returned in a non-sellable condition will not be accepted.

UK Returns and Exchanges

In the UK we offer a free returns label with Royal Mail (download the free return slip here).

Please include your name, order number, the product details and the reason for the exchange or refund. If any of these details are missing, we will not be able to process your request.  We are unable to offer refunds or exchanges for any underwear due to hygiene reasons.

All returns are subject to testing upon receipt - we reserve the right to refuse a refund if the product shows signs of use.

We aim to process exchanges and returns as fast as we can, but during busy periods this can take up to 2 weeks.

If you have any questions, please contact our Customer Service Team at
