San Francisco's favourite Desinger Consignment stores. Rated the best or 5 Stars from the New York Times, GQ, Refinery29, GOOP and many others. One of the most outstanding designer consignment stores in the US for Women and Men. So just what does "Sui Generis" mean, anyway? It's a question we've received many times over the years. A Latin expression meaning "unique; of its own kind," Sui Generis is more than just our namesake, it's a philosophy that informs everything we do. Like a gallery of fine art or rare book store, our meticulously curated consignment stores are the result of discerning eyes, hearts, and minds. Miguel and Gabriel, owners and founders of Sui Generis Inc., humbly set out nearly 10 years ago with a passion for clothing and a desire to create a secondhand retail shopping.
