Loro Piana Trousers: Buyer's FAQ

How can I tell Loro Piana trousers are authentic? We authenticate every pair in-house, and the tells are in the details counterfeiters get wrong. We read the factory label — a genuine one carries a Lotto (lot), Matricola (serial) and Colore code, with the "LORO PIANA S.p.A." header printed crisply, never bleeding into the fabric — confirm the engraved buttons and zip pull, and check the waistband construction, hems and finishing. We feel the cloth: real Loro Piana wool, cashmere and linen have a distinct hand, never flat or synthetic. On recent pieces we verify the Aura Blockchain / NFC certificate. Because genuine labels vary by year and region, we never rely on a single marker — if a pair doesn't pass every checkpoint, we don't list it.

What are Loro Piana trousers made of? Loro Piana trousers are cashmere, featherweight wool, cotton or linen. Every listing states the exact composition and our condition grade.

How should Loro Piana trousers fit? Loro Piana follows Italian sizing, and cuts range from slim to relaxed. Check the waist, rise and inseam we publish on each pair rather than the label size alone.

Are pre-owned Loro Piana trousers worth it? Yes. The build lasts for years, so a pre-owned pair at a fraction of retail is sound value, and every pre-owned piece is graded transparently (Unworn with tags, Unworn, Excellent, Very Good). And every piece is authenticated — if one is ever proven inauthentic, we refund it in full — with a 14-day return policy, so you can buy with confidence.

How to Buy Loro Piana Trousers

From the trousers we inspect, check the hems, knees and seat for wear, the waistband, and the cleanness of the crease. We grade each of these before a pair is listed, new or pre-owned.

Pair Loro Piana trousers with knitwear and loafers, or dress them up under a blazer.

Hang from the cuff or fold along the crease, and steam to refresh. Every pair at Sanpetuna — new and pre-owned — is authenticated by hand and backed by a 14-day return policy; if a piece is ever proven inauthentic, we refund it in full.
