About Unknown Seller

Founded in 2018 in Milton Keynes by two friends, Unknown Seller has its roots in Supreme and Sneaker reselling but has evolved to focus on second-hand designer jackets & coats, ready-to-wear goods, watches and accessories. 

At Unknown Seller, the focus is on finding you the best condition authentic pre-loved items for a fraction of RRP. This is accomplished by our team of skilled authenticators who scour the second-hand market, looking for the next grail and hidden gems. It's also not uncommon for us to offer a fair price on your pre-loved designer.

Unknown Seller hopes to offer an alternative to the world of fast fashion. By dealing with well-made items already in circulation, you are able to buy luxury items below retail and get the opportunity to minimise your carbon footprint without sacrificing your fit.

Going forward we aim to grow and become an established and trusted community within the second-hand market.
