What to check before you buy a designer bag second-hand, and when to call in an expert.
By Shreya S · Last reviewed 15 November 2026
What is the safest way to buy?
New, from the brand’s own stores and website or its authorised retailers. Second-hand, from established resale platforms that authenticate items and offer refunds if a bag turns out to be fake. Be most careful with social media sellers, market stalls and listings that won’t let you see the item or pay securely.
What are the warning signs?
A price far below the going rate is the biggest. Then look closely: uneven, loose or slanted stitching; hardware that feels light, flaky or has blurred engraving; logos that are misaligned, spelled oddly or the wrong font; patterns that don’t line up at the seams; a strong chemical smell; and cheap linings. Compare every detail with photos from the brand.
What are superfakes?
High-quality counterfeits made with real leather and close copies of hardware, which can fool even experienced buyers. Serial numbers, date codes and authenticity cards can be faked too. For expensive pieces, pay for professional authentication, from a specialist service, an expert appraiser or a reputable resale platform, before you buy.
Is buying a fake really a problem?
Yes. Counterfeiting is linked to organised crime and to factories with unsafe conditions, and in some countries, including France and Italy, buyers of counterfeits can be fined. It also undermines the designers whose work is copied. See fashion law and logos and status.
