Corteiz (CRTZ) sells only through surprise, password-protected drops on crtz.xyz, so demand massively outstrips supply — and convincing fakes of the cargos, tees and tracksuits hit the market within days of every release. RareAmour pairs streetwear authenticators with AI to verify your piece from photos: the Alcatraz logo, the mustard woven tags, hardware and stitching. You get a verdict in ~15 minutes to a few hours, plus a free QR digital certificate on anything authentic.
We check the proportions of the Alcatraz island silhouette and the RTW globe mark, and whether screen-prints are crisp and embroidery is dense and even — replicas warp the shape or leave fuzzy, uneven stitching.
Corteiz's mustard-yellow woven label has a specific tone and font weight; fakes run pale or washed-out with thinner, off letters and sloppy edge stitching.
Genuine wash tags print bold and solid with correctly aligned care symbols and sizing; counterfeits go light, blur, misalign the icons or fade after a single wash.
We inspect buckles, snaps, toggles and drawcord aglets for weight, finish and branding — fakes use flimsy, lightweight parts and cheap cord tips.
Seam density on cargos and tees, clean hems, fabric weight and hand — cross-referenced with the actual drop the piece came from and its restock reality.
Corteiz issues no serial numbers and no authentication QR, so there is no database to check a piece against. What you work with instead is the woven neck label with the Alcatraz logo, the inner care label with composition, wash symbols and country of manufacture, and above all the drop history: every garment exists in a finite set of colourways and graphics. An order confirmation from corteiz.xyz or an official pop-up is worth more than any reseller certificate.
Check the weave density, the finish at the edges and whether the label sits centred on the neckband. On genuine pieces the lettering reads cleanly, with no fuzz or dropped loops, and the stitching runs straight.
Composition, wash symbols, country and a batch or size reference identify a production run, not your item. The same reference appears across the whole run, which is exactly why it proves nothing.
Corteiz sells only through its own site and unannounced drops. A colourway or graphic that never released is the fastest and most reliable filter there is.
Labels and tags are the first thing counterfeiters get right. What separates a real piece is the Alcatraz embroidery, the texture of the print, the weight of the fabric and the cargo hardware, all visible in close-up shots.
| What we look at | Authentic | Replica |
|---|---|---|
| Woven neck label | Dense weave, sharp lettering, clean edges, label centred and stitched straight. | Loose weave, blurred letters, off-centre placement, loose threads. |
| Alcatraz logo | Even stitch density, small details still legible, tidy reverse side. | Flat or lumpy embroidery, details lost, knots and puckering on the back. |
| Care label | Clean print, correct wash symbols, stated composition matches how the fabric feels. | Smudged symbols, vague generic composition, stiff paper-like label in the wrong place. |
| Cargo hardware | Substantial drawcords, toggles with no play, even seams on pockets and flaps. | Light plastic toggles, thin cords, crooked pockets, sparse stitching. |
| Provenance | The colourway exists in a real drop and the buyer holds a corteiz.xyz confirmation. | An exclusive colour that never dropped, sold through third-party shops, with a certificate written by the seller. |
Most verdicts land in about 15 minutes, and complex pieces take up to a few hours.
Clear shots of the neck tag, wash/care label, a logo close-up, any hardware and drawcords, plus the full item front and back.
Yes — we never rely on one detail. It's the combination of tag tone, print, logo proportions, hardware and stitching that exposes even the best fakes.
Every item verified as authentic gets a free QR digital certificate you can share or keep as proof.
