LACOSTE Authentication Guide: How to Spot Fakes and Date Tags | RE-USE TOKYO
RE-USE TOKYO
AUTHENTICATION GUIDE
Authentication Basics
Authenticating Lacoste products cannot be done based on a single factor alone.
It is essential to comprehensively examine four key elements: tags, embroidery, stitching, and care labels.
Recent counterfeits have improved logo accuracy, making it risky to judge based on the logo alone.
⚠ Do not rely solely on the logo or zipper. Tags and care labels are paramount.
⚠️ Authentication Criteria Emphasized by RE-USE TOKYO
Tags (Era Consistency): Approx. 40% → Item number format, country of manufacture, material composition, font
Care Labels: Approx. 30% → Material ratio, washing instructions, accuracy of legal markings
Crocodile Logo Embroidery: Approx. 20% → Density, clarity of outline (※ Some recent fakes have high accuracy)
Stitching & Fabric Feel: Approx. 10% → Stitch uniformity, fabric thickness
※ This is an estimated guideline based on experience, and authentication factors may vary depending on the product.

⚠ Important Notes
Tag specifications differ between items for the Japanese market (Sankyo Seiko license) and the international market. Please authenticate after confirming the sales region.
Regarding the crocodile logo: "1400 stitches," "red eyes," and "gradation" vary by era, size, and production factory. Do not use a specific color or number of stitches as a sole criterion.
Regarding zippers: Lacoste uses zippers from multiple manufacturers, including YKK, ECLAIR, OPTI, and unbranded ones. Authentication cannot be based solely on the zipper brand.
DEVANLAY branding: While it can be a reference for era determination, do not use it as the primary basis for authentication.
Regarding items circulated in Korea: Tag specifications may differ for licensed products or parallel imports in the Korean market. Do not judge an item as fake based solely on tag specification differences.
