What Sellier Knightsbridge does

Sellier Knightsbridge is a UK-headquartered luxury pre-loved fashion resale retailer operating through both a direct-to-consumer e-commerce platform and nine physical boutiques. The flagship store is at 6 Cheval Place in Knightsbridge, London, with additional locations across Brompton Road, Motcomb Street, Leeds, Meadowhall (Sheffield), Liverpool, Glasgow, Belfast, and Monaco. The company buys and consigns authenticated second-hand luxury goods — primarily handbags from Hermès (Birkin, Kelly, Constance), Chanel (Classic Flap), Christian Dior, Louis Vuitton, Gucci, and Fendi — alongside designer clothing, shoes, fine jewellery, watches, accessories, menswear, and a children's luxury vertical. The core value proposition rests on an authenticity guarantee backed by a team whose combined experience with the major maisons exceeds 30 years, addressing the counterfeit risk that dominates the secondary luxury market.

The underlying technology is light: the platform is a standard Shopify-style e-commerce storefront with category filtering by brand, condition, size, price, and colour, supplemented by worldwide shipping in GBP, EUR, and USD. The differentiated capability is human authentication expertise, not proprietary software. The supply side runs a three-step consignment model branded as Sellier Selected: consignors upload item details, ship the piece in, and receive payment after authentication. Thematic merchandising collections (New Drops, Wedding Guest, Vacation Dressing, 100 Favourites) and a sub-£500 'Luxury for Less' edit broaden the entry price point alongside ultra-rare Hermès pieces priced above £25,000.

The business model is one-off resale of authenticated luxury items at individually set unit prices, with no subscription component. Customers are affluent individual consumers seeking both rare investment-grade pieces and accessible entry-level luxury; the brand has been featured in Forbes, Vogue, Harper's Bazaar, The Sunday Times, and Tatler. Marketing relies on content (educational brand guides on Hermès hardware, Louis Vuitton icons, investment pieces), email newsletters, and earned media. The company is privately held with no disclosed funding rounds, investors, or revenue figures, and operates with a stated headcount of 1-10 employees.
