Recognising Genuine Gertrude + Gaston: An Authentication Guide
An endearing French brand with a gentle style, Gertrude + Gaston is not a major target for counterfeiters — but when buying pre-owned, you need to be able to tell a genuine piece in good condition from an imitation or an altered item. Here are the useful pointers.
At NB08, every piece is checked and authenticated in our boutique before it goes on sale. The points to check are set out below.
Why check the authenticity of a Gertrude + Gaston piece?
More than counterfeiting, the risk here is an item with no label, altered, or presented under a false name. A quick check of the labels and finishing makes the purchase safe.
Labels and the model name

The Gertrude + Gaston label is woven, with clean typography, accompanied by a detailed composition label. The brand names its models (such as the Gaspar reversible jacket): check that the model exists and matches the piece being offered.
Materials and reversibility
The house takes great care over its materials: soft knits (modal, wool), down jackets with even fill and, above all, reversible pieces whose two sides are finished with equal care — zips usable both ways, clean seams on both sides. A 'reversible' with a botched inner side is not up to standard.
Zips, press studs and finishing
Smooth-running zips, firm press studs, finished drawcords, firm ribbing: the level of finishing must be consistent. Also check the actual condition (pilling, compacted fill), which determines the value of a pre-owned piece.
Price and seller: the warning signs
Be wary of pieces with no label at all or with blurry photos; ask for photos of the labels and of both sides (for reversibles).
