About Known Source
Known Source is a UK-based second-hand fashion marketplace specialising in vintage clothing, streetwear and archive fashion. It gives established vintage specialists a platform to sell through, so both buyers and sellers belong to a trusted community, and expert dealers authentically assess every item before it is listed, which safeguards quality and authenticity.
Away from the website, the company runs physical retail events and dealer residencies, bringing people together through pop-ups and conversations about fashion history. Its Renew feature supports sustainability by letting customers resell what they have bought later on, feeding into a circular fashion economy.
Shoppers can pay by Visa, Mastercard, Amex or PayPal. Gift cards are sold as well, among them the Dans Designer Gift Card, which comes in denominations such as £10 and can be used across the curated marketplace of independent dealers. Signing up to the newsletter brings a first order discount, usually a £10 voucher or a 10% off, which generally applies to the first order only. Known Source also keeps an Instagram and LinkedIn presence.
Refunds can be taken as Shopify shop credit or returned to the original payment method. Credit is reimbursed instantly, while money sent back to the original payment method takes one to three business days to appear, and VIP clients get faster reimbursements once their return requests have been examined and accepted.
