Zegna Blazers & Sport Coats: Buyer's FAQ

How can I tell a Zegna blazer is authentic? We authenticate every blazer in-house, and the tells are in the details counterfeiters get wrong. We check the labels: genuine Zegna tailoring carries clean woven main and composition labels (matching inside the jacket's left inner pocket and, on suits, the trouser waistband) and, notably, no Zegna logo printed across the lining. We look for horn buttons rather than cheap plastic, a canvassed chest and neat, dense stitching, and we confirm the piece is Zegna-made, not merely cut from Zegna cloth by another maker. Most is made in Italy, Switzerland or Spain. Because details vary by era, we never rely on a single marker; if a blazer doesn't pass every checkpoint, we don't list it.

What are Zegna blazers made of? Zegna blazers are cashmere, wool, linen and silk blends, canvassed and finished in Italy. Every listing states the exact composition and our condition grade.

How should a Zegna blazer fit? Zegna follows Italian sizing with a clean cut. A blazer should close cleanly at the chest and sit smooth across the shoulders — check the measurements we publish per piece rather than the label size alone.

Is a pre-owned 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 Zegna Blazers & Sport Coats

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

Pair a Zegna 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.
