Of all the brands we handle, Lacoste might be the one people authenticate the least. The crocodile's so familiar that a quick glance feels like enough, and that's exactly the gap fakers live in. A bad croc will tell you almost everything, but you have to actually look at it.
Quick orientation before the detail: if you only do one thing, study the crocodile embroidery up close and turn the placket inside out. Most of the rubbish falls at that hurdle.
Prefer to buy something already checked? Our Lacoste collection is here. And if it's sizing you're stuck on, what an "FR4" actually is in UK terms, that's a separate post: Lacoste FR Sizing Guide.
The crocodile
A real croc is a proper little piece of embroidery. Jaw open, teeth showing, an actual eye, texture across the body, and it sits raised off the fabric because the stitching is dense. It faces right, tail curling upward, with the red mouth detail on most modern pieces.
The fakes are where it gets obvious. The embroidery goes flat and sparse, the teeth disappear, the eye's a blob or missing, and sometimes the whole animal looks slightly stretched or squashed because they've copied it off a photo rather than the real thing. Then comes the trick I use every time: turn the placket inside out and look behind the chest logo. A genuine one is tidy back there. A high-street fake leaves a bird's nest of loose backing threads.
Labels, country tags and the FR number
This is the next place they come apart. The neck label should be cleanly woven and feel like fabric, not the thin shiny ribbon stuff. Lacoste is legitimately made all over — France, Peru, India, Morocco, others — so the country on the tag doesn't prove anything by itself. What matters is that the printing is flawless: crisp font, even spacing, no spelling or alignment slips. Fakes routinely fluff the wash and composition tags, so read them properly.
You'll also see Lacoste's FR numeric sizing here (2, 3, 4, 5, 6 and up). A real size tag is sharp and correctly formatted; a wonky, blurry one is a flag.
Buttons and stitching
Genuine polo buttons tend to be mother-of-pearl style, and plenty are engraved with "Lacoste" legible, centred, not smeared. Buttonholes should be tight, the twin needlework on seams straight and even. Anything fraying on a piece that's barely been worn is a bad sign.
The piqué test
Classic Lacoste polos are a heavy cotton piqué with that honeycomb texture, and they hold their shape. Knock-offs cut the cost with a thinner poly blend that feels silky or lets light through when you hold it up. Once you've handled a genuine one the difference is hard to unfeel.
Vintage Lacoste is its own thing
Older Lacoste needs a different eye, because the branding's changed repeatedly over the decades. Don't panic at a couple of things that look "off" but are actually correct:
Early pieces often read "Chemise Lacoste" rather than just Lacoste. "Devanlay" turns up on loads of genuine vintage and later stock, that's the licensed maker, not a fake marker. Label fonts, tag layouts and even the croc style shift by era, so it pays to know roughly when the piece is from before you judge it. Made in France is common on older gear but never guaranteed.
Around the listing
Same rules as any brand. Suspiciously cheap, no close-ups, vague description, a seller who won't answer straight, each of those on its own is a maybe, but stack two or three and trust your gut.
What gets faked most
The L.12.12 piqué polos, the big-croc and box-logo tees, the tracksuits and track jackets, and any hyped collaboration, the Netflix "Stranger Things" range being a recent one. High demand pulls in high fake volume every time.
FAQs
Quickest single tell? The crocodile. Flat, toothless or blobby embroidery and you're most of the way to an answer.
Does "Devanlay" mean fake? No. It's the licensed manufacturer and appears on genuine pieces.
Does the country of origin prove it's real? No — Lacoste is made in several countries. Judge by construction and print quality, not the place name.
What's the FR size about? It's the French numeric size. FR4 is roughly a Medium — full breakdown in our Lacoste FR Sizing Guide.
