Loro Piana Blazers & Sport Coats: Buyer's FAQ

How can I tell a Loro Piana blazer is authentic? We authenticate every blazer 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. We confirm the branded buttons and any engraved hardware, look for the soft, largely unstructured construction and hand-finished details Loro Piana is known for, and feel the cloth itself: real Loro Piana baby cashmere and wool have a distinct loft and spring, never a flat or crunchy synthetic hand. On recent pieces we verify the Aura Blockchain / NFC certificate, the strongest guarantee there is. Because genuine labels vary by year and region, we never rely on a single marker — if a blazer doesn't pass every checkpoint, we don't list it.

What are Loro Piana blazers made of? Loro Piana blazers are usually baby cashmere, featherweight wool or cashmere-silk-linen blends. Every listing states the exact composition and our condition grade.

How should a Loro Piana blazer fit? Loro Piana follows Italian sizing and cuts close. A blazer should close without strain at the chest and sit clean across the shoulders — check the measurements we publish per piece rather than the label size alone.

Is a pre-owned Loro Piana blazer worth it? Yes. The build lasts for years, so a pre-owned blazer 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 Blazers & Sport Coats

From the blazers we handle, look at the shoulders and lapel roll, any thinning at the elbows, and that the cloth keeps its spring. We grade each of these before a blazer is listed, new or pre-owned.

Pair a Loro Piana blazer with matching trousers for a soft suit, or dress it down with cotton trousers and a polo.

Hang on a contoured hanger and steam rather than iron to protect the cloth. Every blazer 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.
